[摘要]通過ANSYS動(dòng)力時(shí)程分析，研究加支撐的竹框架結(jié)構(gòu)的抗震性能，并進(jìn)行了支撐布置的優(yōu)化分析。結(jié)果表明：通過布置支撐能夠有效地減小竹結(jié)構(gòu)在地震作用下的側(cè)移，經(jīng)過優(yōu)化支撐布置后的結(jié)構(gòu)不僅能夠滿足我國規(guī)范層間位移角限值的規(guī)定且經(jīng)濟(jì)效益較好。

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
