摘要

根据建筑物不均匀震陷发生机制，提出了建筑物不均匀震陷二维有限元分析方法。采用了不规则荷载下土的残余应变模型及土体逐步软化模型，考虑了土、结构及地震动波形对不均匀震陷的协同作用效果，实现了对建筑物不均匀震陷的时程分析，并通过大型振动台试验对方法的可靠度进行了检验。

Abstract

Based on the mechanism of earthquake-induced differential settlements of buildings

an analytical method of the two-dimensional FEM for estimating the earthquake-induced differential settlement of buildings is presented. Using the model of residual strain of soils under irregular loading and progressively softening model

the method can consider the combined action of the soil

structure and seismic wave more reasonably and can describe the process of the differential settlements of the buildings. The comparison results with large shaking table tests indicate that the new method is reliable.
