高层建筑框架结构与基础地基共同工作的半解析自由振动分析
Analysis on Free Vibration by Semi-analytical Approach for Collaboration of Frame Structure of Tall Building and Foundation
摘要
Abstract
In the paper,the superstructure and its foundation of a tall building frame structure are simplified equivalently and continuously to a three-dimensional model,which is a combination of thin-wall tubes on semi-infinite elastic subgrade.And its dynamic characteristics are computed with the three-dimensional model by semi-analytical approach based on ODE（Ordinary Differential Equation） Solver.It is observed from the computing example that the new method is reasonable and feasible,At the same time,some valuable conclusions are obtained through analyzing the reasonable results of the numerical example.关键词
