摘要
静力弹塑性分析是一种评估结构抗震能力的方法。针对其在不对称结构中的应用进行探讨,提出侧向荷载模式的选择。采用文[3]改进方法二的原理,利用小震下振型分解反应谱法计算结果,引入修正系数,得到了能力谱的修正方法。最后通过一实例说明这种方法的应用。
Nonlinear static analysis is a method to estimate the seismic performance of structures. Several problems about its application in asymmetric buildings, such as the selection of lateral load patterns, are discussed. Using the principle in literature 3 and the results of mode analytical response spectrum, the modified coefficient is led in and the improvement method on capacity spectrum is got. Finally an example is put forward to demonstrate the using of this method.
