摘要(Abstract):

某项目平面为凹凸不规则的"凹"字形平面,在结构顶部布置了连接体,并与主体结构刚接。分析了连接体对整体结构的影响,并对与主体结构刚接的连接体及相关范围进行了中震和大震性能化设计,最后对连接体进行了动力分析。分析结果表明,连接体对主体结构的影响较小,关键构件截面和配筋适宜,满足性能设计的要求;安装调谐质量阻尼器TMD后连接体的动力反应满足要求。
The plane of a project is a concave-shaped irregular plane,with connecting body arranged at the top of the structure to connect with the main structure in a rigid connection way. The influence of the connecting body on the whole structure was analyzed,and performance-based seismic designs were conducted on connecting body to the main structure and relevant range under fortification and rare earthquakes. Finally,the dynamic analysis of the connecting body was carried out. The analysis results show that the influence of the connecting body on the main structure is small,and the key cross section and reinforcement of the key components are suitable to meet the requirements of performance design. The dynamic response of the connecting body meets the requirements after the installation of tuned mass damper( TMD).
