The objective of the paper is to evaluate the reliability of an adaptive version of the. capacity spectrum method for estimating the seismic performance of multistory buckling-restrained. braced frames. The procedure not only can improve the efficiency of estimation of seismic demand, but. it avoids the problems of unconvergence and multiple solutions because it is non-iterative.

Abstract
The objective of the paper is to evaluate the reliability of an adaptive version of the. capacity spectrum method for estimating the seismic performance of multistory buckling-restrained. braced frames. The procedure not only can improve the efficiency of estimation of seismic demand, but. it avoids the problems of unconvergence and multiple solutions because it is non-iterative. Reliability of. the procedure was verified by means of nonlinear dynamic analysis on structures subjected to earthquake. records. The results were finally compared with the procedures proposed in FEMA440-ATC-55.File in questo prodotto:
