本文应用边界数值积分和拉普拉斯变换对粘滞阻尼在土—结构动力耦合中的效应进行了研究。通过拉普拉斯变换建立了在变换空间的结构弹性动力边界积分方程以及粘弹性—弹性间的比拟关关,对具有粘滞阻尼的结构动力问题采用一般无阻尼的弹性动力问题的求解方式进行数值求解。
In this paper, the effect of viscous damping on soil-structure dynamic coupling is studied by using boundary numerical integration and Laplace transform. Laplacian transformation is used to establish the structural elastic-dynamic boundary integral equations in the transformation space and the viscoelastic-elasticity comparison and closure. The solution to the structural dynamic problem with viscous damping is the undamped elastic dynamic problem. Numerical solution.
