Stochastic seismic response of building with shape memory alloy damper

The present study focuses on the estimation of response building structure supplemented with superelastic shape memory alloy (SMA) damper under stochastic seismic excitation. To this end, has been determined using linearization method random earthquakes and control efficiency SMA is compared yield damper. As output, top floor root mean square (rms) acceleration displacement are presented here in study. Response analysis results show presence optimal values strength which minimizes responses. observed, condition strength, to damper, provided 17 % 49 improvements rms displacement. In parametric performed varying stiffness time period structure, earthquake excitation establish superior over
