参照日本某钢筋混凝土框架结构设计实例,按中国抗震规范重新进行框架结构设计,在此基础上,参考日本框架采用钢筋混凝土填充墙的做法,对中国框架也增加钢筋混凝土填充墙,并用静力弹塑性分析和弹塑性动力时程分析进行结构抗震性能对比.结果表明,框架结构中采用钢筋混凝土填充墙是大幅提升框架结构抗震能力的一个有效方法.
A frame structure example designed according to Japanese building standards, is re- designed according to Chinese building standards. The indicators about seismic performance of the two frame structures are compared. Referencing to Japanese frame structure filled with reinforced concrete walls, two new examples of Japanese frame structure without reinforced concrete walls and Chinese frame structure filled with reinforced concrete walls, are added. The four examples are respectively calculated by use of static pushover analysis and elastic-plastic dynamic time-history analysis, and compared on their seismic performance. Comparison results show that the use of frame structure filled with reinforced concrete walls is an effective way to enhance the seismic capacity.
