摘要: 利用考虑节点柔性和二阶效应的二阶弹性分析单元刚度矩阵,采用有限单元法对半刚性钢框架进行了自由振动研究。通过对各算例计算所得自振频率的分析比较,探讨了各种因素对自由振动分析的影响。Abstract: Based on the second-order analysis of elastic element stiffness matrix considering connection's flexibility and second-order effect,a finite element method is used to study free vibration of semi-rigid steel frame.Through the comparison of examples' natural frequency,different factors influencing free vibration analysis are discussed.
