This elastic limit-ultimate strength design procedure for earthquake resistant response of multistory staggered truss framed buildings concentrates the inelastic activity in the chord members in the vicinity of the central open panel of the truss. A detailed description of the design philosophy is presented. Inelastic dynamic responses of two 40-story buildings designed with different levels of elastic lateral force resisting capabilities subject to 1.5 times the El Centro (1940) NS accelerogram are compared. It is shown that this framing system has significant energy absorption capacity and ductile deformation capability.
