In one implementation, a metal deck is provided that includes one or more deck components formed in a contiguous metal sheet. Each of the deck components includes one or more folded ribs formed along the length of the metal deck. Each of the one or more folded ribs are configured such that one or more trusses of a building may fit between the one or more folded ribs. The metal deck may be used to complete the structural diaphragm without using concrete.

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.

Outdoor fitness pavilions, and systems and methods related to the same are provided. The pavilions include a floor substructure including floor support members, pillars distributed about a perimeter of the floor substructure, a roof substructure including roof support members, at least some of which are connected to the pillars. The pavilion includes integrated fitness equipment items connected to at least some of the pillars.

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.

There is provided building structures that are demountable from a first configuration to be reassemblable to the first configuration or another configuration. The building structures include systems and kits for the structure, post anchors, kits for floor structure, method for assembling floor structures, wall and ceiling support systems, electrical junction box supports, and kits for frame assembly.

A building structure including a first building member and a second building member may be connected by a plurality of fasteners, each fastener having a head, a threaded portion having a through hardness of between HRB 70 and HRC 40, a thread-forming portion of at least HRC 50 hardness enabling the fastener to form threads in at least the second steel building member, and a fluted lead portion of at least HRC 50 hardness with a nominal diameter between 70 and 95% of major diameter, such that the fastener is capable of providing a ratio of strip torque to thread-forming torque of at least 3.0 and a ratio of strip torque to drive torque greater than 6.0 when the second steel building member having a thickness of 0.25 inch and the fluted lead portion having at least one diameter within nominal diameter between 80 and 98% of major diameter.

Methods for constructing and a building kit for use thereof are disclosed. The building kit includes a plurality of posts configured for embedding within square apertures of a foundation, wherein the posts have a cross-shaped cross-sectional shape, a plurality of cross-shaped cross-sectional shaped elongated members, a plurality of roof panels, wherein the roof panels include solar cells, and a plurality of wall panels having conforming shape to the cross-shaped cross-sectional shaped elongated members.

The invention comprises a product. The product comprises a foam insulating panel, the panel having a first primary surface and an opposite second primary surface, wherein the foam insulating panel defines at least one recessed channel in the first primary surface, the at least one recessed channel being sized and shaped to provide a mold for a structural reinforcing member. The product also comprises a concrete panel formed on the first primary surface and filling the at least one recessed channel so as to provide a structural reinforcing member for the concrete panel. The product further comprises an elongate anchor member in the foam insulating panel and extending from the first primary surface of the foam insulating panel into the concrete panel. A method of making a composite reinforced insulated concrete structure is also disclosed.

There is provided a prefabricated floor panel (101) for use with a supporting structure (103) including a floor member (105) the floor member (105) defining a floor surface (107) and being adapted to engage with an adjacent similar floor panel (101) and at least one or more strengthening beams (109) configured to engage with the supporting structure (103) in use to support the prefabricated floor panel (101).
