The present anti-ballistic shelter is a reinforced unit configured to comply with both ISO standards for size and weight, and with the U.S. Department of State Certification Standard for Forced Entry and Ballistic Resistance of Structural Systems. Each end and side wall of the unit is reinforced with wall studs that penetrate the unit's structural framework. Even though these wail studs are welded into place, penetration of the wall studs into the framework ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

The modular anti-ballistic shelter system includes two end units and, optionally, additional middle units for a wider structure. End and middle units may also stack atop each other for multi-story structures. Each unit is configured to comply with both ISO standards for size and weight, and with the U.S. Department of State Certification Standard for Forced Entry and Ballistic Resistance of Structural Systems. Each exterior wall of each end unit and each middle unit is reinforced with wall studs that penetrate the unit's structural framework of beams and frames. Even though these wall studs are welded into place, penetration of the wall studs into the beams and frames ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

Building structures can be fabricated at an offsite, and then assembled at the construction site. The building structures can include beams and wall panels having metal attachments. The beams and wall panels can be assembled by coupling the metal attachments, for example, by welding.

Blast resistant shelters and structural designs therefor according to which the structural designs include anchoring systems and manufacturing of the anchoring system. The anchoring systems include at least one bracket with a spiral winding and opposing first and second end portions. The first end portion includes two holes, and the second end portion includes two holes. The spiral winding is disposed between the first end portion and the second end portion.

Apparatus, systems, and methods for securing anchoring posts to a decking surface without the use of a metal plate or washer to redirect force from a single central fastener on an internally mounted anchor, or the use of an externally visible connector. An anchor member having a generally planar upper surface and vertical sidewalls has connection ridges extending out from those sidewalls that correspond to channels formed in the internal sidewalls of a hollow post member. Using a press, the anchor member is pressed into a secured position in the post. A plurality of attachment holes are disposed in a pattern around the anchor member, passing through the body thereof. For installation, a post with the fitted anchor is placed on a decking surface and a plurality of screws are attached to the decking surface to secure the anchor member and post thereto.

A frame using tubular columns and tubular rafters of generally rectangular cross section. Columns are arranged parallel, spaced apart, opposed pairs that are connected by bolted-on girts to form wall frames. Rafters are arranged parallel, spaced apart, opposed pairs that are connected by bolted-on purlins to form roof frames. Inwardly facing sides of columns and rafters have pluralities of castellated holes. Outwardly facing sides of columns and rafters have another plurality of castellated holes. All connections for braces and crane lifts are made in the inwardly facing sides of the columns and rafters. Joints have either a ridge plate or a haunch plates, each plate with two bolt holes that may be pivot holes and additional bolt holes for securing the plates. Base plates have two pairs of parallel vertical spaced-apart flanges, each pair fitting within and releasably attachable to a column. Pairs may be arranged parallel or perpendicular.

A modular agricultural protection structure may be constructed from vertical poles anchored in the ground, and beams and cross-beams welded to the top of the poles to form a top surface of the module. Load support structures may be welded to the beams, cross-beams, and poles, at regular intervals. Cables may be attached to the load bearing structures and used to support netting. A cable and pulley system may be included to retract the netting from over the top surface during climate weather in order for the plants to receive more sunlight. High quality/high strength materials and welding techniques may be used to provide protection even against several feet of snow accumulation without significant sagging of the netting. Clips may be attached between the cables and the netting at different locations on the top surface of the structure to further decrease sagging of the netting.

A composite building system comprising a structural frame and walls which is made of pultrusion fiber reinforced polymer (PFRP) material. PFRP provides increased performance, strength, protection, and longevity for mobile and fixed building structures, enclosures or vehicles, commonly found in residential, commercial, industrial, healthcare, aerospace, government defense, energy, and agriculture sectors. The PFRP material comprises fibers embedded in a resin matrix. Exemplary fibers are glass, carbon, and synthetic fibers. PFRP products can be formed using a pultrusion method that eliminates outgassing. An intumescent fire barrier can be applied to the PFRP to meet National Fire Protection Association fire endurance codes and standards. The composite building system increases personal safety while reducing weight, labor costs, construction time, and total cost of ownership over the life of the structure while being resistant to ballistic, seismic, corrosion, rotting, impact, and insect damage. In addition, a wall and wall assembly consisting of the PFRP material is impervious to water and air and does not require an exterior finish coating. The PFRP wall and wall assembly can be designed to be versatile, allowing for use with both PFRP structural framing and traditional framing materials, such as concrete, steel, and wood.

A bracket assembly comprising a first bracket member associated with a first side of a structural element, a second bracket member associated with an opposed second side of the structural element, and wherein the first bracket member, the second bracket member and the structural element are fastened to one another using one or more fastening assemblies.
