带X型支撑钢筋混凝土框架结构抗震性能分析
|
摘要
为了提高钢筋混凝土框架结构抵抗超设防烈度地震的能力,研究了在框架中合理设置支撑对结构抗震性能的影响。以某8层框架工程为背景,对3种不同的结构方案———无支撑钢筋混凝土框架、带X型钢管支撑钢筋混凝土框架和带X型钢管混凝土支撑钢筋混凝土框架结构在强震作用下的受力性能进行了Pushover分析。结果表明:在钢筋混凝土框架结构中合理设置支撑可以有效提高结构抗侧刚度,增大结构耗能能力和抗震能力,减小结构顶点侧移和层间侧移;不同材料的支撑起到的抗震效果也不相同,对于本文分析模型,合理设置钢管混凝土支撑起到的抗震效果比设置钢管支撑更加明显。
In order to improve the seismic performance of reinforced concrete(RC) frame structure under strong earthquake,the influences of rational arranging bracings on the seismic performances were investigated.Analysis models of 8-story RC frame without bracing,with steel tube X-bracings and with concrete-filled steel tube X-bracings were built,and Pushover analysis of mechanical behavior under strong earthquake of these models was carried out.The results show that the rational arranging bracings in RC frame structure can efficiently increase the structural lateral stiffness,energy dissipation capacity and seismic performance,and significantly decrease the top displacement and the story drift of the RC frame structure.The seismic effects for different material bracings are not the same,and to analysis models in the paper,the concrete-filled steel tube bracings can provide more seismic effect than the steel tube bracings for the RC frame.
