PUSHOVER ANALYSIS OF PLAN IRREGULAR MASONRY BUILDINGS
The paper investigates the seismic response of plan irregular masonry building structures in order to evaluate the magnitude of torsional coupling and the applicability of 3D pushover analysis for assessing the behavior under earthquakes. As a test example a simple plan asymmetric two-storey masonry building is selected. The nonlinear dynamic response obtained under both several generated records and selected earthquake ground motions is initially compared with the one obtained for a symmetric building variant. Subsequently, the nonlinear dynamic analysis results are compared with the pushover analysis results. The pushover analyses are performed up to the maximum top displacement obtained by the nonlinear dynamic analyses (measured at the mass center), computed for each earthquake record separately. The deflection profiles and damage at the stiff and the flexible building sides are compared with the peak response obtained by nonlinear dynamic analysis.
