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 assembled light steel structure energy-saving composite wall in the present invention comprises: a cement board and/or ceramic tile, a column, a support rod, a cross beam, a bottom plate, a diagonal brace and a diagonal draw steel bar. In the thickness direction of the composite wall, the horizontal side of each group of columns is outside the composite wall, a plurality of support rods and diagonal braces are installed between the four second vertical sides of the columns of the each opposite group of columns. In the width direction of the composite wall, a plurality of cross beams and diagonal draw steel bars are installed between the first vertical sides of the column of the adjacent groups of columns. On both sides of the thickness direction of the composite wall, the horizontal sides of the column of the two adjacent columns are provided with a cement board and/or a ceramic tile inserted by a strip fastener and a strip, and the space enclosed by the cement board and the ceramic tile, the cement board and the cement board or the ceramic tile and the ceramic tile is filled with the filler. The assembled light steel structure wall system is simple to assemble, convenient to transport, operate and maintain, energy-saving and heat-preserving, the wall installation and wall decoration is completed at one time.

The present invention discloses a three-dimensional lightweight steel framing system formed by bi-directional continuous double beams. The three-dimensional lightweight steel framing system comprises beams, purlins, columns, wall bodies, floor slabs and lateral resistant mechanism comprises of diagonal support or bracing, wherein the beams are continuous double beams, and the continuous double beams are formed by combination of identical or different continuous single beams, and the continuous single beams are respectively arranged at the both sides of the columns, and the single beams are kept continuous at the junctions with the columns. The three-dimensional lightweight steel framing system simplifies the production of the lightweight steel member, and simplifies the on-site assembly by using bolts and nuts.

A solar array support structure includes a first vertical pile extending from a ground to a first pile end, a second vertical pile extending from the ground to a second pile end, and a first pile cap attached to each of the first and second vertical piles, the first pile cap configured to account for a misalignment of at least one of the first vertical pile and the second vertical pile by providing for adjustable attachment locations for each of the first and second pile ends.

A computer program product comprising: accessing a model of a building, wherein the model is comprised of a plurality of assemblies, wherein the assemblies are comprised of a plurality of members; detecting the assemblies which are identified as roof trusses, wherein the roof truss is identified by the specific members and member internal interfaces and the member properties; analyzing the roof trusses to determine if a roof truss has an external interface with another roof truss; isolating the roof trusses and the plurality of members; and analyzing each of the members of the roof trusses which have external interfaces with other members, wherein the interface is analyzed to determine if the interface is conflicting, wherein a conflicting interface is one where the actual values of the members are inconsistent with a required value.

The present invention is a computer implemented method comprising: accessing a model of a building; isolating a set of roof trusses, wherein the roof trusses are comprised of members; analyzing each of the members and determining the actual properties of each of the members; comparing if the actual properties of the members are within a predetermined tolerance of a set of required properties for each of the members; and generating a list of all conflicting members.

A method of making a virgin joint between at least two separate structural hollow sections in a truss or jacket structure made of the at least two structural hollow sections may include the steps of applying a fiber reinforced polymer wrap around the at least two structural hollow sections in a transitional area, covering and thus bonding together the at least two structural hollow sections, and forming the virgin joint between the at least two structural hollow sections and the fiber reinforced polymer wrap. Welding of the virgin joint between the at least two structural hollow sections is avoided.

A joist chord reinforcement apparatus for a joist having a chord with a first chord end and a second chord end is disclosed that includes a reinforcement rod, first and second end clamp assemblies operable to clamp the reinforcement rod to the first and second ends of the chord respectively, and at least one rod clamping assembly operable to secure the reinforcement rod to the chord between the first and second end clamp assemblies when the first and second end clamp assemblies are clamping the reinforcement rod to first and second ends of the chord respectively. A method of reinforcing the chord of a joist is also disclosed.

A prefabricated pole barn including a truss assembly, a foundation assembly and a roof assembly is disclosed. The truss assembly includes specially made trusses made with galvanized square tubing or red iron tubing. The tubing helps to provide the trusses with added strength and stability. The design of the trusses along with a quickset foundation of the foundation assembly, particularly treated floor support poles of the foundation assembly, and a roof of the roof assembly help to provide with a quickly and easily assembled pole barn. The pole barn is further stronger, more stable and loadbearing in comparison to traditional pole barns using standard bar joist trusses made of wood.

A structural floor system generally consisting of a grid of intersecting modular trusses, pre-stressed wire strand system and concrete decking. U or C-shaped cold-formed or hot-rolled profiles are used to form the prefabricated modular trusses. Assembling the trusses in two-way creates a grid of intersecting trusses. By running the wire strand from the truss grid, the tension force applies to the floor system. A pre-stressed truss grid accompanying with a reinforced concrete slab above, forms a composite structural floor system which is ideal for floor covering in wide spans in multi-story constructions. A method for assembling such a system is also disclosed.
