Structural Analysis
Seismic Loads in Model Codes
The Uniform Building Code (UBC) of the International Conference of Building Officials has been the primary source of seismic design provisions
Seismic Analysis of Cable-Suspended Structures
For short-span structures (under about 500 ft) it is commonly assumed in seismic analysis that the same ground motion acts simultaneously
Screw Connections
Screws are frequently used for connections in cold-formed steel because they can be driven with a hand-held drill, usually without
Section Property Calculations
Because of the flexibility of the manufacturing method and the variety of shapes that can be manufactured, properties of cold-formed sections
Safety Concerns
Safety is the prime concern of steel erectors. Erectors tie-off above regulated heights, install perimeter cable around elevated work sites, and
Roof Loads
In northern areas, roof loads are determined by the expected maximum snow loads. However, in southern areas, where snow accumulation is
Rolled Sections
Hot-rolled sections produced by rolling mills and delivered to the fabricator include the following designations: W shapes, wide-flange shapes with essentially
Rolled Shapes
Hot-rolled, wide-flange steel shapes are the most commonly used members for multistory steel-framed construction. These shapes, which are relatively simple
