- NEED ASAP. BOX the final answer Structural steel buildings frequently are designed with diagonal bracing systems to resist lateral loads (horizontal forces resulting from wind or earthquake loadings). A certain bracing system is subjected to the following loads: dead load = 13.3 kips, occupancy live load = 6.9 kips, roof live load = 1.3 kips, snow load = 1.3 kips, wind load = 150.6 kips, and earthquake load = 161.1 kips. 1.
