Abstract: The composite joist floor system includes joists supported by supporting members. Corrugated steel decking is positioned over the joists such that the corrugations are substantially perpendicular to the joists. Self-drilling, self-tapping, stand-off screws are spaced along the length of the joist, aligned with the deck corrugations. These stand-off screws provide the required shear transfer between the joist and concrete slab to form a composite floor system. The placed concrete encapsulates the upper non-threaded shank portions of the stand-off screws and the end of the joists. After the concrete has cured, the resultant system comprised of steel joists, steel decking, stand-off screws, and concrete, act together to form a composite system with greater load carrying capacity and less vertical deflection. The stand-off screws connect the joist upper chords to the concrete slab allowing the joist and concrete slab to act as a unit, by transferring shear between the two joined components.

Abstract: A ductile shear reinforced bar layout applied to reinforced concrete shear wall structures comprises several vertical reinforced bars, several horizontal reinforced bars, several connecting reinforced bars, a shear reinforced bar, and several reinforced bars, wherein the vertical reinforced bars and the horizontal reinforced bars are intersected to form a plane, the shear reinforced bar structure and the reinforced bars are firmly disposed on the plane, two adjacent planes are connected by the connecting reinforced bars, pouring concrete to the shear reinforced bar connected on the planes and the shear reinforced bar structure being wrapped around by the concrete are to form the shear wall with the RC. Due to irregular vibrations from earthquake, the surface of the wall is cracked along the directions with larger shear forces. Hence, adding the shear reinforced bar structure can avoid cracks and promoting the ability to anti-vibration.

Abstract: A precast composite flooring system utilizes girders and floor panels having steel lower structures placed in tension and concrete upper structures places in compression. Openings through a stem wall allow ducts, pipes, and conduits to be run therethrough. The system provides reduced weight over conventional precast or pour in place systems, allowing further reduction in the weight and size of other building components. The floor deck does not use tensioning strands, allowing openings to be formed at nearly any stage of construction and with reduced concern over cutting steel reinforcement. The floor panels and girders bolt together and bolt to a steel column frame, allowing for more efficient assembly.

A series of joist supports are connected to the channel and a series of joists, formed of a light gauge cold formed steel, are connected to the joist supports and extend outwardly from the box. Decking is supported on the joist. Concrete is poured into the channel to form a reinforced header or beam, and concrete is also poured onto the decking to form a concrete floor. Together, the concrete floor and header form a monolithic concrete structure that enables the joist to be misaligned with studs.

Abstract: A structural reinforcement system that is implemented during the preparation of the area when pouring a concrete slab such as, but not limited to, commercial and residential floors, patios and driveways. The system includes digging foundation holes that are selectively disposed around the area being poured. The system further includes positioning steel bars above the ground in the lower twenty-five percent (25%), rather than upper fifty percent (50%) as known in the prior art, of the concrete being poured. In this manner, the poured concrete encapsulates the lattice in the lower twenty-five percent (25%) of the concrete when it hardens. As a result, the system improves and often removes the possibility of any cracks in the concrete and eliminates the need for saw joints. In addition, due to the stability created with the addition of strategically placed foundation holes, less concrete is required on the job resulting in a significant cost savings.

Abstract: A building form that uses two building panels made of a rigid board and rigid insulation are supported by light gauge framing members and integrating two adjacent building panel molds forming a ribbed chamber into which concrete can be poured. The building panels when jointed together form a depression within the mold panel for a concrete rib when concrete is poured over the building panels. In addition, each of the building panels when separated by another fire resistant board thereby forming a space between the panel molds forming a wider forming mold which becomes an integral part of the building panel. The separated building panels also allow for mechanical means to be distributed. Additional forming means can be added for a wider and deeper forming structure. Several different transverse support beams can be used to increase the panel mold structural strength.
