A mathematically heavy chapter. Elliott guides the reader through global analysis of skeletal frames, including second-order effects (P-delta), sway sensitivity, and the concept of "diaphragm action." If you are searching for a PDF just for the formulas on moment distribution in pinned-base columns, this is the chapter.
He introduces the critical concept of "diaphragm action"—how a precast floor acts as a horizontal deep beam to transfer wind loads to vertical cores. precast concrete structures by kim elliottpdf
