A structural reinforced composite construction mat includes a plurality of composite plastic beams that are ganged together to define the mat, with a plurality of flitch plates disposed between at least some of the plastic beams to provide additional strength and rigidity to the mat. The plastic beams may be made of a composite material have a generally rectangular cross-section. The flitch plates have a width (vertical height) when disposed between adjacent beams that is less than the width (vertical height) of the beams, such that the flitch plates may be recessed below and above the top and bottom surfaces of the mat, respectively. A plurality of rods extend in the lateral direction through the beams and plates to compress the beams and plates against each. The flitch plates may be metal or fiber-reinforced resin and may further include slotted holes to allow the beams to retract lengthwise in response to environmental changes.

Various embodiments disclosed herein relate to moment-resisting frames, kits for assembling such moment-resisting frames, and methods of repairing such moment-resisting frames. In an embodiment, a moment-resisting frame includes a beam connected to a column using a moment-resisting connection. The moment-resisting connection may include at least one exterior doubler plate (“EDP”) that is connected to the column and two or more connectors that are connected to both the beam and the EDP. In some embodiments, the moment-resisting frame may require less welding than conventional beam-to-column connections. Additionally or alternatively, such a moment-resisting frame may eliminate the need for components typically used in conventional beam-to-column connections (e.g., continuity plates).

A gusset plate assembly for use in connecting at least two beams to a hollow tubular column in a building. The gusset plate assembly can receive said at least two beams in a biaxial orientation of said beams. The gusset plate assembly comprises gusset plates sized for transferring the weights of said at least two beams and their reaction forces and bending moments from the application of severe load conditions acting on the building to the hollow tubular column. At least one of the gusset plates receives a portion of a second of the gusset plates. A joint penetration groove weld joining the first and second gusset plates together allows the gusset plate assembly to be free of welds on its internal corners. A method of assembling a gusset plate assembly is also disclosed.

The present invention relates to a mounting structure comprising a structural member having a first surface adapted to engage a support and at least one first flange extending outwardly from a second surface, wherein the first surface is distal from the first flange; and at least one securing member comprising at least one second flange extending outwardly from a surface of the securing member, wherein the securing member is operable to juxtapose with the structural member via the first surface, and engage with the structural member to secure a side of a panel between the first flange and the second flange. The present invention also relates to a mounting structure assembly and method of assembling the same.

A full-moment column collar is disclosed, including four collar flange components and four collar corner components. Each collar flange component includes an upper transverse element and a lower transverse element, connected by a bridging member. Each collar corner component includes first and second expanses defining a corner and a standoff portion extending from the corner, the standoff portion having a distal T-shaped structure. Each collar corner component is configured to connect two adjacent collar flange components, and each collar corner component has a multi-axis alignment structure extending from a bottom end portion for vertically positioning a lower transverse element of a respective collar flange component.

A structural yielding link, particularly for use in an eccentrically braced frame arrangement or in a linked column frame arrangement having a first end having a means for connecting to a face of a first beam and a second end having a means for connecting to a face of a second beam; a first variable cross-section portion and a second variable cross-section portion extending from the first end and from the second end, respectively; and a constant cross-section portion joining the first variable cross-section portion and the second variable cross-section portion.

There is disclosed a modular platform assembly including a plurality of legs (18), a plurality of floor beams (20a,b,c), and a plurality of connectors (24a,b,c,d) for connecting the legs (18) and the floor beams (20a,b,c). Each said connector (24a,b,c,d) comprises: a downwardly open blind recess (59) with a closed top end (60) and an open bottom end (62); and an upwardly open blind recess (64) with a closed bottom end (66) and an open top end (68). The legs (18) are mounted into the downwardly open blind recesses (59) of the connectors (24a,b,c,d) and the floor beams (20a,b,c) are mounted into the upwardly open blind recesses (64) of the connectors (24a,b,c,d) such that the legs (18) extend downwardly from the floor beams (20a,b,c).

A truss clamp assembly includes a lower support member extending in a lateral direction, a vertical rod coupled to the lower support member and extending in a vertical direction that is transverse to the lateral direction, a first engagement portion coupled to the vertical rod and spaced apart from the lower support member in the vertical direction, and a second engagement portion coupled to the vertical rod and spaced apart from the lower support member in the vertical direction, where the second engagement portion is spaced apart from the first engagement portion in the lateral direction, such that the first engagement portion and the second engagement portion define a gap positioned between the first engagement portion and the second engagement portion in the lateral direction.
