地下结构地震反应计算的改进的反应位移法
Improved response displacement method for evaluating seismic responses of underground structures
摘要
Abstract
It is difficult to accurately determine the stiffness coefficient of foundation spring in the response displacement method. Furthermore, different foundation springs are not relevant, and the interaction between the structure and the soil cannot be actually reflected, causing error in the load distribution on the soil-structure contact. Taking the foundation spring as the research object, an improved response displacement method is proposed, abandoning the traditional loading method in the finite element analysis process and loading the force all around the structure to solve the stiffness coefficient of foundation spring. Compared with the existing response displacement methods, the calculated results of the improved method is reasonable, and the proposed method has higher computational efficiency.关键词
