摘要
本文件对无侧移结构推导了计入单元局部惯性力影响的修正单元刚阵。文中算例表明,在不增加自由度的前提下采用修正单元进行自由振动分析,结构的频率计算精度可以明显提高。
In this papre, the modified element stiffness matrix of the structures without sidesway is presented, including the acting of local inertial force of the element. The numerical results in the paper show that the modified element is used to analyse the free vibration, and the accuracy of the structural frequency is greatly raised at no increasing the freedom.
