［摘要］為了研究傳統(tǒng)風(fēng)格建筑鋼筋混凝土框架結(jié)構(gòu)的整體抗震性能，設(shè)計(jì)了比例為1/4的典型單層歇山屋頂框架結(jié)構(gòu)縮尺模型，并進(jìn)行了振動(dòng)臺(tái)試驗(yàn)研究。介紹了試驗(yàn)?zāi)Ｐ偷脑O(shè)計(jì)與制作、相似比的確定以及配重的布置等，描述和分析了模型結(jié)構(gòu)在7度多遇、設(shè)防、罕遇地震，8度設(shè)防、罕遇地震和9度罕遇地震階段的試驗(yàn)破壞過程和動(dòng)力特性、加速度及位移反應(yīng)。同時(shí)，采用PMSAP計(jì)算軟件對(duì)原型結(jié)構(gòu)進(jìn)行了彈性和彈塑性時(shí)程分析。結(jié)果表明計(jì)算結(jié)果在彈性階段與試驗(yàn)結(jié)果比較符合，而在結(jié)構(gòu)屈服后，兩者的結(jié)果相差較大。最后，給出了該類結(jié)構(gòu)的主要破壞部位，為傳統(tǒng)風(fēng)格建筑的結(jié)構(gòu)設(shè)計(jì)提供了思路。

Abstract: 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.

Keywords:traditional style building; frame structure; shaking table model test; seismic performance
