Evaluating the Efficiency of Current Nonlinear Static Pushover Procedures on Estimating Torsion effect for asymmetric High-rise Buildings

In present paper, the capability of current nonlinear static pushover methods on estimating the torsion effects of existing buildings has been studied. One real high-rise building with dominant torsion mode has been performed pushover analysis using two classic nonlinear static pushover procedures. Time history analysis has also been performed using tremor monitoring ground acceleration records. According to the comparison between the results of pushover analysis and time history analysis, the efficiency of MPA procedures and N2 method on estimating torsion effect for asymmetric high-rise buildings have been evaluated.
