Abstract

In this article, it is tried to overcome one of the weaknesses of the current assumptions used in the ordinary pushover analysis. This includes the assumption in which it is assumed that “the first mode controls the response of the structure and this mode remains unchanged after it undergoes to inelastic range”, this assumption is inadequate especially in tall buildings with long natural period of vibration. It seems that the invariant lateral loads used in this procedure cannot depict these effects. Here, by presenting the modal pushover analysis (MPA) and considering three LATERAL LOAD PATTERNS related to the three first modes of the structural deformation, it is shown that how the higher modes affects the accuracy of seismic response of MRF compared to ordinary method introduced in FEMA273 and non-linear Response History Analysis.
