Nonlinear Dynamic Time History Analysis for Pile-soil (Soft Support Model)-structures
摘要
Abstract
Based on the pile-soil soft support model,a simplified interaction finite element analysis model of soil-structure was established,and the nonlinear dynamic time history analysis was conducted for this model under different seismic excitations and different conditions of the pile-soil.The result shows that,under certain ground motion and soil-foundation conditions,the nonlinear effect of the upper struc-ture can be greater than fixed base assumption,and pile-group-soil soft support model also influences the weak layer position on the upper structure.The analysis results and the existing test results are in good a-greement.By using structural units to solve complex computational problems in geotechnical engineering, designers can carry out dynamic time history analysis and seismic evaluation for the superstructure quickly, accurately and efficiently.关键词
