【摘要】 型钢骨架与混凝土楼板组合模块化房屋结构是一种装配式建筑结构,与传统框架结构存在较大差异,其抗震性能和节点性能研究是重点。本文建立了该组合模块化房屋结构的理想刚接-铰接节点计算模型与半刚性节点计算模型,进行了七度至九度罕遇地震作用下结构体系的Pushover静力弹塑性分析,得到了结构构件塑性变形的过程以及结构体系的抗震性能指标。采用动力时程分析方法得到结构在不同地震波下的位移和内力响应,进行了模块之间连接构件的承载力验算。更多还原

【Abstract】 Modular combined building structure is a kind of pre-fabricated building structures,there is difference between the traditional frame structure and modular building structures.Its seismic performance and joints’ performance research are the key points. An ideal rigid-hinge joint and semi-rigid joint computational model are built for the combined modular building structure. Pushover analysis of 7、8 and 9 intensity earthquake are conducted on both two computational models. The plastic sequence of the structure members and the structural seismic performance are obtained. The displacement response under three different seismic wave and the internal force response of each structure members are computed by the Time-history analysis. Bearing capacity of the connecting member is checked.更多还原
