[摘要]靜力彈塑性分析是一種評估結(jié)構(gòu)抗震能力的方法。針對其在不對稱結(jié)構(gòu)中的應(yīng)用進(jìn)行探討,提出側(cè)向荷載模式的選擇。采用文[3]改進(jìn)方法二的原理,利用小震下振型分解反應(yīng)譜法計算結(jié)果,引入修正系數(shù),得到了能力譜的修正方法。最后通過一實例說明這種方法的應(yīng)用。

Application of nonlinear static analysis in antiseismic design of asymmetric buildingsWei Lian, Wang Sen, Wang Zhiyuan, Zhou Qingxiao(Shanghai Weilian Structure Design Institute Shenzhen Office, Shenzhen 518034,China)
Abstract: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.
Keywords:nonlinear static analysis; asymmetric buildings; lateral load mode; capacity spectrum
