eam column joints, all member stresses are primarily axial. When diagonal brace connections are eccentric to the joints, members are subjected to bending and axial stresses. Diaphragms consist of concrete or metal deck with concrete fill and are stiff relative to the frames. Walls may consist of metal panel curtainwalls, glazing, brick masonry, or precast concrete panels. When the interior of the structure is finished, frames are concealed by ceilings, partition walls, and architectural furring. Foundations consist of concrete spread footings or deep pile foundations. Structural deSign criteria Figure 2-2 S steel moment frames 2-
Figure 2-2 S2 steel braced frames Light frame steel structures are pre-engineered and prefabricated with transverse rigid steel frames (see Figure 2-26). They are onestory in height and the roof and walls consist of lightweight metal, fiberglass, or cementitious panels. The frames are designed for maximum efficiency and the beams and columns consist of tapered, built-up sections with thin plates. The frames are built in segments and assembled in the field with bolted or welded joints. Lateral forces in the transverse direction are resisted by the rigid frames. Lateral forces in the longitudinal direction are resisted by wall panel shear elements or rod bracing. Diaphragm forces are resisted by untopped metal deck, roof panel shear elements, or a system of tension-only rod bracing. 2- 2 Structural deSign criteria
