[摘要]通过ANSYS动力时程分析，研究加支撑的竹框架结构的抗震性能，并进行了支撑布置的优化分析。结果表明：通过布置支撑能够有效地减小竹结构在地震作用下的侧移，经过优化支撑布置后的结构不仅能够满足我国规范层间位移角限值的规定且经济效益较好。

Abstract: To study seismic performance of bamboo frame structure with braces, ANSYS dynamic time-history analysis was used and the braces layout optimization analysis was carried out. The results indicate that the lateral displacement of bamboo structure is effectively reduced through the arrangement of the braces under seismic action and that bamboo structure with braces can not only satisfy the inter-story displacement limit in code regulations but also has appreciable economic benefits after brace-layout optimization.

Keywords: time history analysis； bamboo structure； optimization； inter-story displacement
