（深圳華森建筑與工程設計顧問有限公司廣州分公司，廣州510045）[摘要] 洲頭咀A7棟樓為高位轉換的超限高層。本文基于梁柱塑性鉸和剪力墻纖維模型，利用MIDAS Buliding軟件實現了超高層建筑結構的彈塑性時程分析，驗證結構是否滿足“大震不倒”的設防水準要求。研究了在大震作用下結構將出現的破壞模式、塑性發(fā)展特點等，尋找結構薄弱部位和薄弱構件，提出相應的加強措施。計算結果表明，在給定地震波的罕遇地震作用下，結構整體受力性能良好，能滿足罕遇地震下的抗震性能目標。

( Huasen Arclutectural & Engineering Designing Consultant Ltd., Guangzhou 510045, China)Abstract: Based on the theory of plastic hinges( beams and columns) and fiber model (walls),elastic-plastic time-history analysis is performed on the super-high A7 buliding of Zhoutouzui by MIDAS Building software under the scarce earthquake load. It was determined whether the structure is satisfied with the standard to guarantee no collapse under major earthquake. The weakness parts or components of the structure were found out. Corresponding strengthened measures were put forward in design process. Calculation results indicate that the structure has excellent seismic behaviors when affected by specified major earthquake wave, and can reach the requirement of seismic performance under the actiong of the rarely earthquake.
