［摘要］通过对单跨单层的空间异形柱框架模型在低周反复水平荷载作用下的伪静力推覆试验，研究空间异形柱框架的工作性能、破坏机制及其弹塑性阶段的抗震性能。结果表明，该异形柱框架表现出较好的抗震性能，但其抗震性能受水平荷载方向变化的影响较大。设计时要特别注意其节点部位的加强。

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
