（西安建筑科技大學(xué) 西安 710055）[提要] 針對上海市某實際工程，進行了三榀鋼筋混凝土異形柱框架1/2比例模型擬靜力試驗，研究了這種結(jié)構(gòu)在低周反復(fù)水平荷載作用下的受力特點、變形和耗能能力以及破壞機理等。分析比較了異形柱框架與填充墻異形柱框架以及填充墻異形柱框架與實心磚填充墻普通框架在抗震性能等方面的差別。
[關(guān)鍵詞] 異形柱 擬靜力試驗 耗能能力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.
Keywords: special-shaped columns; pseudo-static tests; energy dissipation capacity
