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.

A modular building structure that utilizes a standard, unmodified intermodal shipping container both for transport of the structural components and as an integral element of the method of construction. A modular structure kit is enclosed in the shipping container, which can be transported using all means that are standard for ISO containers. Using the preferred method of construction, the shipping container can be situated without heavy equipment. Once situated, the shipping container provides the primary support for a permanent elevated structure composed of unique components, assembled using conventional building techniques without the necessary use of heavy or specialized equipment.

A building system and method of using the same may include forming a modular, collapsible, reusable frame and applying at least one sheathing layer on the modular, collapsible, reusable frame. The system and method may include applying at least one mesh layer on the at least one sheathing layer; applying at least one concrete layer on the at least one mesh layer; curing the at least one concrete layer; and removing the modular, collapsible, reusable frame. The system and method may form at least one continuous wall and roof portion to make up a monolithic structure defining an interior cavity.

A system and method for securing a roof truss to a load bearing wall is disclosed. A strap is attached to a roof truss at one end and extended to the top of a load-bearing wall. A buckle is placed over the strap to pinch the strap between the vertical and horizontal arms of the buckle. The end of the strap is wrapped back toward the vertical side of the roof truss and a flat plate is placed to pinch the free end of the strap between the buckle and the flat plate. Screws are placed through holes in the flat plate and corresponding holes in the buckle to attach the system to the top of the load-bearing wall. The system and method of the invention provides both horizontal (lateral) resistance and uplift resistance, thus resisting horizontal (lateral) forces while at the same time providing uplift resistance.

A disassemblable roof framing structure for use on camping habitations comprising structural attachment brackets for connecting a transverse beam with an existing frame on the habitation. The attachment brackets are adjustable width-wise by sliding along the length of the transverse beam so as to adjust to the width of the habitation. The transverse beam has one extension member for each end of the transverse beam. The extension members being extendable so as to adjust to the width of the existing frame. The extension members have attachment brackets at their distal ends from which perpendicularly extend vertical studs running upwardly along the side walls of the habitation and up towards the roof of the habitation. Each vertical stud is capped by an interface bracket, and each interface bracket connects to a top beam. There is at least one top beam on each side of the habitation to which are connected triangular rafter frames by way of rafter connector brackets.

The present invention is a method for accessing a model, wherein the model incorporates a plurality of roof truss assemblies, wherein the assemblies are comprised of a plurality of members; detecting at least one interface between at least two roof truss assemblies, and wherein the interface type is detected; recording, by at least one processors, a interface type, wherein a set of required values based on the interface type are identified; calculating a set of actual values associated with the interface; comparing if the set of actual values is within the required values; identifying a modification to at least one roof truss assembly involved in the interface; incorporating the modification into the model; and analyzing the model for newly created interfaces between a set of members of the model.

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 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.
