Nowadays, architects tend to create more complex structures than before. So engineers should become compatible with these ideas especially when they would be located on hazarded areas. For gaining this, two different kinds of 10-story structures for considering Different degrees of coupling between translational and torsional modes, have created from a symmetric structure, considering effects of Soil-Structure Interaction (SSI). Then a series of Nonlinear Response History Analysis (NLRHA) under bidirectional ground motions, are performed to calculating seismic demands of them. Finally, modal pushover analysis (MPA), modified consecutive modal pushover procedure (MCMP) and some lateral load pattern that recommended in FEMA-356 are performed to estimate seismic demands of them. Comparing results of NLRHA and other methods indicate that MCMP procedure is able to catch a good estimation of seismic demands of one way asymmetric plan building.
