摘要
对一 1/ 6比例 12层大开间钢筋混凝土异形柱框架结构模型进行了振动台试验 ,探讨结构的地震反应和破坏形态。采用杆模型编制了钢筋混凝土异形柱框架结构的弹塑性时程分析程序 ,经比较 ,计算结果与试验值吻合较好。探讨了肢长肢厚比对该体系结构性能的影响 ,并提出了相应的设计建议。
A model with 1/6 scale of a 12-story big-bay RC frame with special-shaped columns (FSSC) was designed. The dynamic behavior of the model structure was studied by a simulated earthquake test on a shaking table. The dynamic responses of the model were studied. A computer program was designed to analyze the nonlinear dynamic characteristics of the FSSC structure, and the results were compared with those from shaking table test. In fact, these results accord with each other quite well. The properties of the FSSC structures with different length/width ratio of the columns were studied, and suggestions are also made for this kind of structures.
