［摘要］通過(guò)對(duì)單跨單層的空間異形柱框架模型在低周反復(fù)水平荷載作用下的偽靜力推覆試驗(yàn)，研究空間異形柱框架的工作性能、破壞機(jī)制及其彈塑性階段的抗震性能。結(jié)果表明，該異形柱框架表現(xiàn)出較好的抗震性能，但其抗震性能受水平荷載方向變化的影響較大。設(shè)計(jì)時(shí)要特別注意其節(jié)點(diǎn)部位的加強(qiáng)。

［關(guān)鍵詞］空間異形柱框架；偽靜力推覆試驗(yàn)；彈塑性；抗震性能

Abstract:Pseudo-static test of single span and single story 3D-frame with special-shaped columns was carried out under the reversed cyclic horizontal loading with low frequency. The service behavior and failure mechanism of the 3D-frame with special-shaped columns were studied, and the aseismic performance of the 3D-frame with special-shaped columns at elasto-plastic stage was explored by experiment results. The results show that the aseismic performance of the 3D-frame with special-shaped columns is good, which affected seriously by direction of horizontal load. Beam-column joints are needed to strengthen during the design.

Keywords:3D-frame with special-section column；pseudo-static test；elastic-plastic；aseismic performance
