Abstract

Abstract

The principle and procedure of 3D pushover analysis with N2 method are studied,Then,3D pushover analysis is performed for a 12-story reinforced concrete asymmetric frame structure,whose result is evaluated by the elastic-plastic time history analysis.The comparative result shows that the N2 method with reversed-triangle and simplified modal lateral load pattern can predict the more rationally maximal interstory drift,and that the pushover's result underestimates the elastic-plastic interstory torsion rotations.
