Abstract:

Assessment of different nonlinear static procedures (NSP) on estimation of seismic demands of threedimensional buildings with bi-axial eccentricity in plan subjected to two components of ground motion is investigated. Their estimates are compared to the exact results, obtained from nonlinear time historyanalysis. The selected procedures are: extended N2, modal pushover analyses (MPA), modified MPA (MMPA), practical MPA (PMPA), Multimode pushover and response spectnun analysis (RSA) extended to bi-directional excitation. A three-story asymmetric building subjected to different bidirectionalexcitations is considered. It is demonstrated that the accuracy of the aforementioned procedures results depends on the type of considered ground motions
