【摘要】 在以往的钢框架结构设计尤其是抗震设计中,通常将梁柱节点处理为完全的刚接或理想的铰接.但是在实际框架中,梁柱节点表现出半刚性.结合工程实例,采用结构动力时程分析的方法,在钢框架结构抗震分析中考虑半刚性连接的问题,并与传统方法进行了对比.更多还原

【Abstract】 In the seismic analysis of steel frames, it is often assumed that the connections between columns and beams are either rigid or pinned. However, the connections have been proved to be semi-rigid theoretically and practically. Seismic time-history analysis is used in this paper taking into connections of semi-rigid and the result reveals that steel frames with semi-rigid have superior seismic capability.更多还原
