axial stiffness and the tributary area of columns and walls and apply the optimum distribution of additional reinforcement to reduce differential column shortening in reinforced concrete high rise buildings . learn more easily design steel framing wall bridging lateral bracing vertical deflection seismic drift headers and sills hold downs moment resisting shear wall anchors floor and roof joists & roof trusses learn more progressive collapse progressive collapse aka disproportionate collapse occurs when a local failure spreads throughout a structure from element to element eventually resulting in the collapse of either the entire structure or a disproportionately large part of it . progressive collapse is caused by an abnormal or extreme loading event typically due to accidental impact faulty construction foundational failure or violent changes in air pressure ie blast . learn more optimize blast design for ufc els offers a new advanced level of nonlinear static or dynamic
