Abstract
In order to explore the influence of the change of foundation spring parameters on the dynamic response of the structure,this paper firstly takes the calculation results of the dynamic time history method as a reference solution,compares and analyzes the solution forms of dif-ferent foundation spring parameters,and determines the optimal solution method.On this basis,the parameters of the overall foundation spring and the spring at different positions of the structure were adjusted,and the influence of each parameter on the internal force and displacement response of the structure was analyzed and determined.The analysis results show that compared with the change of the top spring parameters,the changes of the side springs and the bottom spring parameters have a greater impact on the internal force and deformation of the structure,and on the whole,the values of the spring parameters at each position of the structure increase by 100%～400%,and the structural deforma-tion and the internal force changes at the key positions are about 16%～43%.关键词
