结构在不同基础嵌固条件下动力反应分析

Analysis of Dynamic Response of Structures with Different Consolidated Bases

运用大型有限元分析软件ANSYS对基础嵌固条件不同的结构建立三维有限元模型,在土与基础的接触面建立接触单元,对比分析结构在不同基础固结条件的动力特性以及非线性地震反应。结果表明,不同基础固结条件对结构动力特性和地震反应的影响是显著的,从而为结构抗震设计提供一定的指导。

In this paper, three-dimensional finite element models are set up for structures with different consolidated bases with ANSYS software. Contact elements are created at the contact surface between the soil and foundation. The dynamic behavior and Seismic nonlinear responses of the differently based buildings are analyzed. The results show that the dynamic behavior and seismic responses of the structure are greatly influenced by different base consolidation conditions, providing useful reference for anti-seismic structure design.
