[提要]  根据异形柱纯框架、异形柱框-桁架和异形柱填充墙框架的低周反复试验结果，对比了三种结构形式在承载能力、抗侧刚度以及耗能方面的差异，并分析了支撑和填充墙对框架的作用，及其作用的变化过程。

On the basis of experimental research on the model of frame, frame-truss and filled-frame with special-shaped columns, the difference of lateral stiffness, load-carrying capacity ancl energy dissipation is studied among three types of structure. This paper also analyses the contribution of truss and filled-wall and the change of this contribution with the increase of displacement.
Keywords:  special-shaped columns; frame; frame-truss; filled-wall; load-carrying; stiffness; energy dissipation
