摘要
采用一种适用于筏形和箱形类基础的地基离散模型，建立上部结构－基础－地基系统在时域内的运动方程。采用时程分析法对高层筒体结构进行地震反应分析。讨论了不同场地，不同地震输入以及基础埋深等因素对结构地震反应的影响。
In this paper,the equations of motion of a structure foundation soil system in time domain are derived by adopting a discrete model of soil which is suitable for raft and box foundations.Based on the equations,the seismic response analysis of a high rise tube structure is performed by using the time integration.The effects of some factors such as different sites,input motion and embedment depth on the response of the structure are discussed.
