随机激励下考虑SSI效应的TMD-结构控制参数优化设计
Optimal design of control parameters of TMD -structures with SSI effect under stochastic excitation
摘要
Abstract
TMDs are main devices of seismic control and wind resistance control of high-rise buildings.The compatibility of a structure's frequencies and TMD parameters plays a decisive role in the control effect.In the existing codes, the influence of soil on the upper structure's frequencies is neglected, so that the vibration control of TMD-structure is out of line with the actual engineering situation.In this paper, the maximum inter-storey displacement is taken as the control index, and the optimization algorithm and the theory of probability density method combining with ten layers of TMD concrete frame structure parameters optimization are used to study soil-structure interaction (SSI) effects on the TMD structure of the control effect, and the optimal design parameters of the TMD structure under random excitation.This work provides a reference for the optimal design of TMD building structures.关键词
