摘要
为了研究传统风格建筑钢筋混凝土框架结构的整体抗震性能,设计了比例为1/4的典型单层歇山屋顶框架结构缩尺模型,并进行了振动台试验研究。介绍了试验模型的设计与制作、相似比的确定以及配重的布置等,描述和分析了模型结构在7度多遇、设防、罕遇地震,8度设防、罕遇地震和9度罕遇地震阶段的试验破坏过程和动力特性、加速度及位移反应。同时,采用PMSAP计算软件对原型结构进行了弹性和弹塑性时程分析。结果表明计算结果在弹性阶段与试验结果比较符合,而在结构屈服后,两者的结果相差较大。最后,给出了该类结构的主要破坏部位,为传统风格建筑的结构设计提供了思路。
In order to study the seismic performance of a reinforced concrete frame of traditional style building,a 1/4 scale model of a typical one-story frame with gable and hip roof is designed and tested on the shaking table. The design and making of test model,similitude relationship,the layout of the weight were introduced. The failure process,dynamic property,acceleration and displacement of the model structure under different earthquake levels were described and analyzed. The elastic and elastic-plastic time history analyses of the model were also made using the analysis program for PMSAP. The results show that the calculated results are in agreement with the experimental results in the elastic stage,and after the frame yields,all results are quite different. Finally,the main damage parts of this kind of structure were given,which provides an idea for the structural design of traditional style building.
