【摘要】 Push-over分析方法近年来在地震工程界引起广泛兴趣,我国新的抗震设计规范已将这种方法作为大震作用下结构弹塑性分析的一种方法。影响Push-over分析结果的准确性有许多因素,其中对结构施加的侧向加载模式至关重要。采用不同的侧向加载模式对一座12层不规则异形柱结构进行Push-over分析,并将分析结果与非线性时程分析的结果进行比较,由此给出该异形柱结构Push-over分析加载模式选取的建议。更多还原

【Abstract】 Push-over analysis has caused much interest in the field of earthquake engineering in recent years, and it is suggested as a nonlinear analysis method of the structural deformation under severe earthquake in the new seismic design code in China.The determinacy of push-over analysis result is influenced by many factors, the most important one of which is lateral load pattern exerting to structure.In this paper,push-over analysis using different load patterns imposed on12 layers of irregular special-section structure.The results by push-o- ver analysis are compared with those by nonlinear time history analysis,and some suggestions on the selection of load patterns for irregular special- section structures are given.更多还原
