[提要]  针对上海市某实际工程，进行了三榀钢筋混凝土异形柱框架1/2比例模型拟静力试验，研究了这种结构在低周反复水平荷载作用下的受力特点、变形和耗能能力以及破坏机理等。分析比较了异形柱框架与填充墙异形柱框架以及填充墙异形柱框架与实心砖填充墙普通框架在抗震性能等方面的差别。

The pseudo-static tests of three l/2-scale models R.C. frames with special-shaped columns have been conducted. The load-bearing properties, deformation and energy dissipation capacity and the mechanism of failure for the structure are studied. It makes a comparison in aseismic behavior between frames with special-shaped columns and infilled frames consisting special-shaped columns and common infilled frames. Aseismic behavior of the structure is evaluated. Research results indicate that the frame with the special-shaped columns possesses better aseismic behavior. The structure can form better failure mechanism under rare earthquake.
