2. Hollow structural section - Wikipedia

   en.wikipedia.org/wiki/Hollow_structural_section

   HSS is only composed of structural steel per code. HSS is sometimes mistakenly referenced as hollow structural steel. Rectangular and square HSS are also commonly called tube steel or box section. Circular HSS are sometimes mistakenly called steel pipe, although true steel pipe is actually dimensioned and classed differently from HSS. (HSS ...

3. Structural steel - Wikipedia

   The steel columns will be connected to the slab by bolting and/or welding them to steel studs extruding from the surface of the poured concrete slab. Pre-cast concrete beams may be delivered on site to be installed for the second floor, after which a concrete slab may be poured for the pavement area.

   More specifically, it gives detailed application rules to determine the static design resistances of uniplanar and multiplanar joints in lattice structures composed of circular, square or rectangular hollow sections, and of uniplanar joints in lattice structures composed of combinations of hollow sections with open sections (space frames and ...

5. Metal fabrication - Wikipedia

   en.wikipedia.org/wiki/Metal_fabrication

   Workers welding in parking garage. Welding is the main focus of steel fabrication. [8] Formed and machined parts are assembled and tack-welded in place, then rechecked for accuracy. If multiple weldments have been ordered, a fixture may be used to locate parts for welding. A welder then finishes the work according to engineering drawings (for ...

6. Lattice girder - Wikipedia

   en.wikipedia.org/wiki/Lattice_girder

   The lacing elements are typically attached using either hot rivets or threaded locator bolts. As with lattice girders, laced struts and ties have generally been supplanted by hollow box sections, which are more economic to produce with modern technology. In some case seismic retrofit modifications replace riveted lacing with plates bolted in place.

7. Integrated framing assembly - Wikipedia

   en.wikipedia.org/wiki/Integrated_framing_assembly

   As 14-gage galvanized hollow metal frames, IFAs are installed prior to the pouring of the concrete, are capable of being anchored into the footer, and function as the method of blocking out the opening and the frame that under previous methods would be installed later. Thus, not only do they keep the opening’s dimensions firm during concrete ...
