DETAILED DESCRIPTION

(40) It is to be understood that the following disclosure provides many different embodiments, or examples, for implementing different features of various illustrative embodiments. Specific examples of components and arrangements are described below to simplify the disclosure. These are, of course, merely examples and are not intended to be limiting. For example, a figure may illustrate an exemplary embodiment with multiple features or combinations of features that are not required in one or more other embodiments and thus a figure may disclose one or more embodiments that have fewer features or a different combination of features than the illustrated embodiment. Embodiments may include some but not all the features illustrated in a figure and some embodiments may combine features illustrated in one figure with features illustrated in another figure. Therefore, combinations of features disclosed in the following detailed description may not be necessary to practice the teachings in the broadest sense and are instead merely to describe particularly representative examples. In addition, the disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not itself dictate a relationship between the various embodiments and/or configurations discussed.

(41) Embodiments of the disclosed anti-ram vehicle barrier 10 are configured to be crash-rated by certifying agencies such as DOD, DOS, American Standard Test Method (ASTM), British Standards Institution (BSI) and International Standardization Institution (ISO). Vehicle barriers are tested by crashing a motor vehicle from an attack side in a perpendicular direction into the barrier. The vehicle barrier is rated based on the test vehicles weight, the speed of impact, and the penetration of the vehicle (e.g., the cargo bed) beyond the pre-impact inside edge of the barrier. For example, a K (SD-STD-02.01) or M (ASTM F2656) designates a medium duty vehicle with a gross weight of 15,000 pounds (6810 kg). The speed ratings include K4/M30 for traveling at 28.0 to 37.9 miles per hour (mph); K8/M40 traveling at 38.0 to 46.9 mph, and K12/M50 traveling at 47.0 mph and above. The penetration ratings include P1 for less than or equal to 1 meter (3.3 ft.); P2 for 1.10 to 7 m (3.31 to 23.0 ft.); and P3 for 7.01 to 30 m (23.1 to 98.4 ft.). For example, an M50-P1 crash barrier is designed to stop a medium duty truck traveling 50 mph with a penetration distance of 3.3 feet or less. Some embodiments of the disclosed anti-ram vehicle barrier 10 may be engineered crash-rated but not crash tested. Some embodiments of the disclosed anti-ram vehicle barrier 10 may not be engineered crash-rated or crash tested.

(42) FIG. 1 is a plan view of an exemplary passive anti-ram vehicle barrier (AVB), generally denoted by the numeral 10, arranged in a post and beam arrangement according to aspects of the disclosure. FIG. 2 is an elevation view of passive anti-ram vehicle barrier 10 illustrated in FIG. 1. AVB 10 is configured to stop a motor vehicle 11 traveling from an attack side 13 that crashes into AVB 10 from penetrating beyond a selected distance from AVB 10 into the protected or asset side 15. In a post and beam arrangement, braces are not used to achieve an anti-ram vehicle barrier rating. FIGS. 1 and 2 illustrate an embodiment configured to meet the crash criteria to achieve an M50-P1 rating under ASTM F2656 or a similar rating.

(43) In FIG. 1, AVB 10 is positioned between a protected or asset side 15 and a motor vehicle 11 approaching AVB 10 from an attack side 13. AVB 10 includes a continuous beam 12 positioned above ground level 17. AVB 10 may include one or more truss sections 14. In the illustrated examples, truss sections 14 are illustrated at the terminal ends of a longitudinal length of continuous beam 12. It will be recognized by those skilled in the art with the benefit of this disclosure, that two or more longitudinal lengths of continuous beam 12 may be arranged together to form an extended length of need. Beam 12 is formed of interconnected beam sections 16. Adjacent beams sections 16 are connected at joints 18. In some embodiments, joints 18 are pivoting connections that permit a degree of pivoting movement between adjacent beam sections 16 or a beam section and a post when beam 12 is impacted by a motor vehicle.

(44) Posts, generally denoted by the numeral 22, are connected to beam 12, for example, to support beam 12 above ground level and to provide tension to mitigate lift of beam 12 in response to the impact of the motor vehicle. Posts 22 are metal members and may take various forms including I-beams, round or rectangular (e.g., square) members. Posts 22 may be arranged in a line or crash post configuration, identified specifically with reference number 22a, connected to beam 12 at a joint 18 and between adjacent beam sections. In a post and beam arrangement, braces do not extend from a crash post to the ground in the direction toward asset side 15. Posts 22 may be arranged in an end or corner post configuration, identified specifically with the reference number 22b, connected to continuous beam 12 at a joint 18. Posts 22 may be arranged in an intermediate configuration, identified specifically with reference number 22c (see, e.g., FIGS. 14-15), connected directly to beam 12 at an intermediate position between joints 18. Some or all of posts 22 may be used to support an ornamental fence structure, e.g., a chain link section.

(45) Crash posts 22a and end posts 22b provide the structural strength in a post and beam arrangement to resist vehicle penetration to meet standardized test criteria. In some embodiments, crash posts 22a and end posts 22b are in the same vertical plane as beam 12. Intermediate posts 22c are located within the beam span between joints 18 that connect adjacent beam sections 16 or beams sections 16 to crash posts 22a or end posts 22b. Intermediate posts 22c may be connected to the beam, for example, to provide vertical support to beam 12 between relatively long spans between crash posts and to provide tension to the beam relative to the foundation to prevent lift of the beam when impacted by a vehicle. AVB 10 illustrated in FIGS. 1 and 2 does not have intermediate posts due to the short span between the adjacent crash posts 22a.

(46) FIGS. 1 and 2 illustrate a linear section of AVB 10 extending between opposing end posts 22b that meets the M50-P1 crash testing criteria under ASTM F2656. The terminal ends 20 of a linear section of beam 12 are connected to the respective end posts 22b. An example end post 22b is illustrated in FIGS. 4-6. A corner end post, although not shown, may be similarly configured for beam sections to extend in two different directions. As will be understood by those skilled in the art with the benefit of this disclosure, connection joints 18 (e.g., beam to crash or end post, or beam to beam) may allow vertical movement of the interconnected elements relative to one another to accommodate grade changes along the length of the barrier. In the illustrated example, the height from grade to beam center is 35 inches+/?3 inches for grade change between crash posts 22a. In some embodiments, beam 12 can accommodate a grade change of about 11 degrees at connection joints 18 providing a maximum grade change of 22 degrees at each crash post 22a. The concrete foundation is a minimum 3500 psi, and in an example, reinforced with No. 3 and No. 5 rebar. In the illustrated example of an M50-P1 barrier, the spacing between adjacent crash posts 22a is approximately 28 feet and the beams sections 16 are interconnected at crash posts 22a. For reference, a single connector plate is referred to as a male connector, or male end, and a double connector plate arrangement is referred to as a female connector or a female end. In an exemplary AVB 10, beam sections 16 may be constructed for example of W6?25 or W6?20 beams, end posts 22b of HSS (hollow square sections) of 12?12?0.5 ASTM A36 steel tube, crash posts 22a of W14?61 beams, and the various connector plates 28, 40, 54 by 1-to-1.5-inch ASTM A572 Gr. 50 steel plate.

(47) In the embodiment of FIGS. 1 and 2, AVB 10 includes trusses 14 and end posts 22b. With additional reference to FIGS. 3, 4, 4A, and 4B, trusses 14 include a kicker brace 24 that extends from end post 22b substantially in-line with beam 12, and below beam 12, to a foundation post 26. In an exemplary embodiment, kicker brace 24 may be constructed of W6?25 or W6?20 beam and foundation brace post 26 of 8?8?0.375 tubular steel. As illustrated for example in FIGS. 1 and 2, truss kicker brace 24 and foundation post 26 are located substantially vertically below beam 12 as opposed to extending laterally away from the longitudinal axis of beam 12. In some embodiments, AVB 10 may not include a kicker brace (e.g., truss) at end post 22b. For example, a post and beam AVB 10 constructed in according to aspects of FIGS. 1 and 2, with the exception of an end section kicker brace, or truss, may achieve a rating below M50-P1 rating, such as a M50-P2, M50-P3, M40-P1, M40-P2, M40-P3, M30-P1, M30-P2, or M30-P3 rating.

(48) FIGS. 5 and 6 illustrate an exemplary embodiment of an end post 22b. End post 22b is constructed, for example, of 12?12?0.5 structural steel. A connector plate 28 is directly attached to end post 22b. Connector plate 28 includes a vertical hole 30 for disposing a pin 32 such as illustrated in FIG. 4A. In this example, connector plate 28 is a 1.25-inch-thick steel plate.

(49) FIGS. 7, 7A-C, 8, 8A-B, 9, and 9A-B illustrate the connection of adjacent beams sections 16 (e.g., FIGS. 10-13) at a crash post 22a. This connection of beam sections 16 at joints 18 to crash post 22a are configured for example to meet the M50-P1 crash test rating. The illustrated crash posts 22a provide beam connection joints 18 on opposite sides of crash post 22a (e.g., opposite sides of beam web 34). Crash post 22a is secured in the ground and oriented such that beam web 34 extends perpendicular to the longitudinal axis of beam sections 16 with an attack side flange 36 located on attack side 13 of AVB 10 and asset side flange 38 positioned on asset side 15 of AVB 10. Adjacent beam sections 16 are connected to crash post 22a and to each other through a beam connector plate 40, also referred to as a beam-post connector plate 40. In this example, beam-post connector plate 40 is a steel plate (e.g., 1 to 1.5 inches thick) having spaced apart pin holes 30, illustrated individually as holes 30a, 30b in which pins can be disposed to connect beam sections 16 to the connector plate. Joint 18 can also permit vertical displacement of the connected members relative to one another to account for grade level changes along the length of AVB 10.

(50) In the illustrated example, beam-post connector plate 40 is a unitary (single structure) that extends through a slot 42 in web 34 proximate to the top end 27 of post 22a, and is welded 44 to web 34, positioning pin holes 30a, 30b that are spaced apart along a longitudinal span 46 on opposite sides of web 34, see, e.g., FIGS. 8A-B, 9. Using two or more connector plates will not depart from the scope of this disclosure. Longitudinal span 46 extends substantially coaxially with the longitudinal axis of the continuous beam. In the illustrated examples, pin holes 30 are located closer to attack side flange 36 than to asset side flange 38 and are located longitudinally outside of the ends of crash post flanges 36, 38. In this embodiment, beam-post connector plate 40 has a lateral span 48 extending perpendicular to longitudinal span 46 and having a length approximately equal to the length of web 34 of crash post 22a and lateral span 48 has a width 50 (FIG. 9) proximate to one-half of the flange, i.e., the length of the flange from the web to the outer end of the flange such that lateral span 48 substantially matches and fills the cross-section area defined between the attack flange 36, asset flange 38, and web 34 (FIG. 8B). Thus, beam connector plate 40 fills the cross-sectional area of crash post 22a on one side of web 34 and on the opposite side of web 34 beam connector plate 40 does not extend the complete lateral distance between flanges 36, 38. In a less-than M50-P1 crash rating embodiment, see, e.g., FIG. 20B), beam-post connector plate 40 may not have a lateral span 48 that extends the full distance between crash post flanges 36, 38.

(51) In the M50-P1 rated AVB embodiment illustrated in particular in FIGS. 1 and 2, the individual beam sections 16 are connected together at crash posts 22a and not interconnected at intermediate positions between crash posts 22a as may be performed in some embodiments. For example, AVB 10, illustrated in FIGS. 14 and 15, includes joints 18 that are positioned at intermediate positions in the beam span between crash posts 22a, see, e.g., FIG. 19.

(52) FIGS. 10-13 illustrate exemplary beam sections 16. Beam section 16 includes an I-beam 52 having one or more connector plates 54, e.g., warp plates, positioned at opposing ends 52a, 52b. Each warp plate 54 includes a warp end 56 in direct contact with I-beam 52 and a vertical hole 30 for positioning a pin 32 as shown for example in FIGS. 7 and 7A. Beam section 16 illustrated in FIGS. 10, 11 and 13, includes two vertically separated connector plates 54 at each end 52a, 52b and may, therefore, be referred to as a female-female beam section. In the illustrated exemplary beam sections 16, a metal housing 58 is attached on the bottom end of the lower connector plate 54 below vertical holes 30. Housing 58 may have lateral opening 60 to align with a cross-hole in the pins to pass a bolt to lock the pin in position. For example, with reference to FIGS. 7 and 7A, a pin 32 is disposed in beam connector plates 54 and crash post connector plate 40 to form a pivotal joint 18 allowing relative rotational movement between pin 32 and at least one connector plates 40, 54. A cross-pin 62, such as a carriage bolt, is positioned through lateral opening 60 into pivot pin 32 to lock the pin in place and prevent unauthorized removal.

(53) FIGS. 14 and 15 illustrate a linear section of an exemplary post and beam type anti-ram vehicle barrier (AVB) 10. AVB 10 includes a continuous longitudinally extending beam 12 formed by a plurality of interconnected beam sections 16 extending between opposing end posts 22b. The terminal ends 20 of a linear section of beam 12 are connected to end posts 22b by pivotal connections 18. AVB 10 illustrated in FIGS. 14 and 15 is configured to meet for example the M40-P2 crash testing criteria under ASTM F2656. An example end post 22b is illustrated in FIG. 16. A kicker brace is not connected to end post 22b as used in the embodiment illustrated in FIGS. 1 and 2. A corner end post, although not shown, may be similarly configured for beam sections to extend in two different directions. As will be understood by those skilled in the art with the benefit of this disclosure, the connection points (joints 18) may allow for vertical movement of the interconnected elements to accommodate grade changes along the length of AVB 10. In the illustrated example, the height from grade to beam center is 35 inches+/?3 inches for grade changes between crash posts. In some embodiments, beam 12 can accommodate a grade change of about 11 degrees at each connection 18 providing a maximum grade change of 22 degrees at crash posts 22a (connections 18 on each side of the crash post). The concrete foundation is a minimum 3500 psi, and in an example, reinforced with No. 3 and No. 5 rebar. The spacing between adjacent crash posts 22a is approximately 246 feet in the illustrated exemplary M40-P2 rated AVB 10. Beam sections 16 are interconnected by pivotal connections 18 at crash posts 22a (FIG. 17), at end post 22b (FIG. 16), and at intermediate positions within the beam span between adjacent crash posts 22a (FIG. 19). In some embodiments, crash posts 22a and end posts 22b are located in the same vertical plane as the longitudinally extending beam 12. Intermediate post 22c may be located in a different vertical plane, i.e., in front of or behind, then beam 12. For reference, a single connector plate is referred to as a male connector or male end, and a double connector plate arrangement is referred to as a female connector or a female end. Intermediate posts 22c may also be connected to beam 12 between adjacent pivotal connections 18 (see, e.g., FIGS. 18, 18A). As shown in FIG. 18A, intermediate post 22c is located in a different vertical plane from beam 12. Intermediate post 22c is located in a vertical plane on asset side 15 of the vertical plane of beam 12. The individual beam sections 16 (FIG. 23) may have a longer length than the individual beam sections used in other crash test rating or not rated embodiments.

(54) In an exemplary AVB 10, beam sections 16 (e.g., FIGS. 23-25) may be constructed of W6?25 or W6?20 beams, crash posts 22a constructed of W14?61, W14?30, or W14?38 beams, end posts 22b by HSS (hollow square sections) of 12?12?0.5 ASTM A36 steel tube, intermediate posts 22c of W13?5.7 beams, and various connector plates 28, 40, 54 constructed of 1-to-1.5-inch ASTM A572 Gr. 50 steel plate.

(55) Another difference between exemplary AVB 10 illustrated in FIGS. 14 and 15 and exemplary AVB 10 illustrated in FIGS. 1 and 2, is the connection of adjacent beam sections 16 at crash post 22a. An exemplary pivotal connection 18 of beam sections 16 to a crash post 22a is described with reference to FIGS. 20, 20A, 20B, 21, 21A, 21B, and 22.

(56) Crash posts 22a provide beam pivotal connection points on opposite sides of crash post 22a (opposite sides of beam web 34). Crash post 22a is secured in the ground and oriented such that web 34 extends perpendicular to the longitudinal axis of beam 12 with an attack side flange 36 located on attack side 13 of AVB 10 and asset side flange 38 positioned on asset side 15 of AVB 10. In the illustrated examples, beam connector plate 40 is a steel plate (e.g., 1 to 1.5 inches thick) having pin hole 30 in which a pin 32 (see, e.g., FIG. 17) is disposed to connect beam sections 16 to beam connector plate 40. In the illustrated example, beam connector plate 40 is a unitary (single structure) that extends through a slot 42 in web 34 and is welded to web 34, positioning pin holes 30a, 30b on opposite sides of web 34, see, e.g., 20A, 20B. Using two or more connector plates will not depart from the scope of this disclosure. In the illustrated examples, pin holes 30 are located closer to attack side flange 36 than to asset side flange 38 and are located longitudinally outside of the ends of crash post flanges 36, 38.

(57) With reference to FIGS. 22 and 22A, a slot 42 is formed in web 34 of crash post 22a extending from proximate to attack side flange 36 and terminating in this example less than the mid-point of web 34. Beam connector plate 40 (FIGS. 21, 21A, 21B), which is a unitary structure in this example, has a longitudinal span 46 that extends a length greater than the length of the crash post flanges 36, 38 and pin holes 30 are spaced apart on along longitudinal span 46. Longitudinal span 46 extends substantially co-axially with the longitudinal axis of AVB 10. In this example, the length of lateral span 48, extending perpendicular to longitudinal span 46, is substantially constant along the length of longitudinal span 46 and the length of lateral span 48 is less than the length of web 34.

(58) Beam connector plate 40 includes an indentation 64 and a tang 66 located on opposite edges of lateral span 48 and proximate to the mid-point along longitudinal span 46. Indentation 64 and tang 66 serve to position beam connector plate 40 relative to web 34 of crash post 22a. Indentation 64 is sized to dispose the flange-to-web taper 68 (FIG. 20B, 22A) on attack side flange 36 and tang 66 adds the material and width removed by indentation 64. Once positioned, beam connector plate 40 may be, for example, welded in place.

(59) FIGS. 23-25 illustrate exemplary beam sections 16. Beam section 16 includes an I-beam 52 having one or more connector plates 54, e.g., warp plates, positioned at opposing ends 52a, 52b. Each warp plate 54 includes a warp end 56 in direct contact with I-beam 52 and a vertical hole 30 for positioning a pin 32 as shown for example in FIGS. 16, 17, and 19. Beam section 16 illustrated in FIG. 23 includes two vertically separated connector plates 54 at each end 52a, 52b and may, therefore, be referred to as a female-female beam section. FIGS. 24 and 25 illustrate a female-male beam section 16. In the illustrated exemplary beam sections 16, a metal housing 58 is attached on the bottom end of the lower connector plate 54 below vertical hole 30. Housing 58 may have a lateral opening 60 to align with a cross-hole in the pins to pass a bolt to lock the pin in position. For example, with reference to FIGS. 16, 17, and 19, a pin 32 is disposed in the connector plates to form a pivotal joint 18. A cross-pin 62, such as a carriage bolt, is positioned through lateral opening 60 into pin 32 to lock the pin in place and prevent unauthorized removal.

(60) An exemplary method for creating a vehicle barrier includes installing a longitudinally extending beam positioned vertically above a ground level and separating an asset side from an attack side, the beam comprising beam sections a crash post positioned in a same vertical plane as the beam, wherein adjacent beam sections are pivotally connected to the crash post. The method may also include crash testing the vehicle barrier by ramming a vehicle traveling in a direction from the attack side toward the asset side into the beam.

(61) Conditional language used herein, such as, among others, can, might, may, e.g., and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that some embodiments include, while other embodiments do not include, certain features, elements and/or states. Thus, such conditional language is not generally intended to imply that features, elements and/or states are in any way required for one or more embodiments or that one or more embodiments necessarily include such elements or features.
