摘要
基于索—梁混合有限元理论,分析索桥在水平冲击载荷作用下的动态特性,分析中采用修正刚度法求解非线性有限元运动方程,得到有价值的结果。
In this paper, on the basis of mixed finite element theory of cable-beam, we have studied cable bridge's dynamic properties under level shock load. Non-linear finite element eqations are solved with modified stiffness method and valuable results are given
