［摘要］對新天地國際大廈塔A高層框架-剪力墻結(jié)構(gòu)進(jìn)行了靜力彈塑性分析。計(jì)算結(jié)果表明，結(jié)構(gòu)在罕遇地震作用下，部分構(gòu)件屈服。最大層間位移角為1/193，滿足規(guī)范規(guī)定的變形要求，并對結(jié)構(gòu)性能進(jìn)行評估。利用小震作用下振型分解反應(yīng)譜法的計(jì)算結(jié)果，提出能力譜小震性能點(diǎn)的周期修正法。

Abstract:The static nonlinear analysis was conducted on tower A of New World International Building, which is a complex frame-shear wall structure. The results show that parts of structural members are yielding under rare earthquake. The biggest story drift is 1/193 which can satisfy deformation demands of design code, and the structure capability is assessed. According to the results of mode-superposition response spectrum method under small earthquake, advance modified period method of performance point on capacity spectrum curve was put forward.
Keywords:static nonlinear analysis; target displacement; capacity spectrum curve; performance point
