(北京邁達(dá)斯技術(shù)有限公司，北京100044)[摘要] 基于梁柱塑性鉸和剪力墻纖維模型，利用MIDAS Building軟件實現(xiàn)了超高層建筑結(jié)構(gòu)的彈塑性時程分析。結(jié)合該結(jié)構(gòu)研究了在大震作用下結(jié)構(gòu)將出現(xiàn)的破壞模式、塑性發(fā)展特點等，并與彈性分析進行了對比，說明彈塑性分析更能反映實際情況，能對結(jié)構(gòu)的抗震性能給出較為合理全面的評價，并對工程設(shè)計給出指導(dǎo)。

( Beijing MIDAS Technology Information Co.,Ltd,. Beijing 100044, 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 business-living building in Beijing by MIDAS Building software under the scarce earthquake load. Failure Modes and plastic zone development are researched according to the feature of the structure. Through the comparison with the elastic analysis, it is considered that evaluation on the structure can be deduced from the elastic-plastic analysis more reasonably and comprehensively, and there will be better instruction to the projects.
Keywords: dynamic elastic-plastic analysis; MIDAS Building; fiber model
