| 中文摘要 | 由于缺乏计算理论和方法,大多数半刚性节点按刚性节点进行设计,与实际情况相差很大。本文采用有限元分析的方法,将半刚性连接节点视为弹簧单元,通过通用有限元软件ANSYS建立有限元模型进行时程计算分析,研究了节点刚度对多层钢框架结构抗震性能的影响。计算结果表明,采用了半刚性连接的钢框架结构,相对于理想刚接的情况,结构的自振周期和振型都有很大变化,在地震作用下结构的底部剪力明显减小,动力响应变化很大。在钢框架分析和设计中,应考虑半刚性节点的影响。; Because of the absence of calculation theory and design method for the semirigid end-plate connection,it is still calculated and designed as rigid connections in our country,which leads to the significant difference between the calculation result and the real stressed state of the end-plate connection.Using the initial connection stiffness and the moment-rotation(M-) curve,the experiment and finite element method are obtained,and taking the semirigid end-plate connection as a spring element,a FEM model is set up by ANSYS to calculate and analyze with elastic time-history method in this paper.The dynamic properties of the steel frames with semirigid connections are discussed,and the influence of semirigid connections on the multi-story steel frames design is studied.The result shows that the steel frames with semirigid connections are different from that with rigid connections.The behavior of the frames is affected by the flexibility of the connections,and their influences can not be ignored in the steel frames design and analysis.; 国家自然科学基金(50578083); 清华大学基础研究基金(JCqn2005006) |
