Concept explainers

Steel Framing

A steel frame consists of a skeleton frame structure comprising of horizontal I-beams and vertical steel columns fitted in a rectangular grid building construction to brace the floors, walls, and the roof of the building held onto the frame. Due to the implementation of this methodology, the construction of the skyscrapers was feasible.

Question

Select the most economical size for the girders that satisfies the length-to-depth ratios for wide-flange beams. Note that the beams should
span the longer distance of the bay, and the girders should span the shorter distance. Assume that the beams and girders are pinned at both
