摘要:
为揭示倒V形钢支撑加固RC框架在罕遇地震作用下的性能,建立了4层RC框架结构及在RC框架结构上后加钢支撑的结构模型,并对模型进行了PUSHOVER分析.从基底剪力-顶点位移曲线、楼层位移曲线及出铰顺序等方面对结构在罕遇地震作用下的抗震性能进行了评估.结果表明,在罕遇地震作用下,后加倒V形钢支撑的RC框架结构达到性能点时的基底剪力较原RC框架结构大,顶点位移较原RC框架结构小;钢支撑作为第一道抗震防线能吸收大部分的地震能量,对梁、柱构件能起有效的保护作用;此外,钢支撑对抗连接倒塌也有较大的现实意义
Abstract:
In order to reveal the performance of RC frame structure with inverted V-shape steel brace under function of rareearthquake,4-layer RC frame structure and the RC structure with inverted V-shape steel brace as well as PUSHOVER on model is performed. The evaluation on anti-seismic performance is performed under function of rare earthquake for structure from such aspects as base shear-top displacement curve, floor displacement curve and hinged out mechanism. The results show that under function of rare occurrence earthquake, the base shear while RC frame structure with inverted V steel brace reaching the performance point is greater than the one of original RC frame structure, and the top displacement is less than the one of original RC frame structure. As the first anti-seismic defensive line, the steel brace can absorb most earthquake energy to play the effective protection for beam and column elements. Additionally, the steel brace is provided with greater practical significance for resisting the progressive collapse
