چکیده مقاله:

In prescriptive seismic design codes, quantification of seismic performance factors (R, Ω, Cd) for new structural systems is decisive step. One of the recent introduced structural bracing systems is called Strong-Back System (SBS), which is a hybrid of a conventional inelastic system and an essentially elastic steel truss designed to distribute demands uniformly. The purpose of this study is to evaluate these factors for SBS. To this end, series of nonlinear static and dynamic analyses are conducted and the derived parameters are compared with the accepted values proposed by FEMA-P695. The results indicated that R=6 can be appropriate value for SBS
