［摘要］以高295m的長富金茂大廈為例，檢驗了整體結(jié)構(gòu)在中震作用下的反應(yīng)是否滿足抗震要求。中震作用下對各受力構(gòu)件分別采取相應(yīng)量化的方法分析其性能狀態(tài)：對連梁，分析其剪切屈服比值和彎曲屈服比值，控制兩者數(shù)值大小實現(xiàn)大震時連梁剪切屈服后于彎曲屈服的性能目標(biāo)；對剪力墻和框架柱，對軸力和彎矩受力狀態(tài)采用N-M包絡(luò)曲線法驗證，對剪切屈服狀態(tài)采用規(guī)范的計算公式復(fù)核；對框架組合梁，其彎曲屈服驗算采用彎矩-曲率曲線驗算；對伸臂桁架上下弦，分別考慮軸力和彎矩的共同作用，采用N-M曲線驗算；對伸臂桁架腹桿，其軸力屈服驗算方法采用鋼結(jié)構(gòu)規(guī)范的計算公式復(fù)核。上述驗算結(jié)果表明該結(jié)構(gòu)在中震下能滿足擬定的中震性能目標(biāo)。

Abstract:Changfu Jinmao Building with a height of 295m was taken as an example to check out whether the overall structure design can meet the seismic requirements under moderate earthquakes. The performance status of each mechanical component was quantified under the impact of moderate earthquake. The shear yield ratio and flexural yield ratio of coupling beam were analyzed and controlled to realize the performance target that coupling beam shear yield falls behind flexural yield. The status of axial force and moment of shear wall and column were checked out by N-M envelope curve. Shear yield state was checked by standard formulas. Flexure yield of composite beam was checked by moment-curvature curve. Axial force and moment of upward and downward chord of outrigger were checked by N-M curve. Axial yield of outrigger web was checked by calculation formulas in the steel structures code. Results from above calculations show the structure can meet the assumed performance target under moderate earthquakes.

Keywords: moderate seismic performance design; performance status; shear yield ratio; flexural yield ratio
