[提要] 根據異形柱純框架、異形柱框-桁架和異形柱填充墻框架的低周反復試驗結果,對比了三種結構形式在承載能力、抗側剛度以及耗能方面的差異,并分析了支撐和填充墻對框架的作用,及其作用的變化過程。
[關鍵詞] 異形柱 框架 框-桁架 填充墻 承載力 剛度 耗能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
