空间巨型框架结构与地基基础共同工作的自由振动简化分析
A simplified analysis for free vibration of interactions between subgrade- foundation and superstructure of space mega frame
摘要
Abstract
Adopting space mega frame that composed by the mega column and mega beam on elastic subgrade, built its foundation and itself on elastic subgrade model which is semi infinite elastic subgrade with equivalent stiffness, and then three-dimensional analysis model is established. The whole mass of structure is acted on the floors of mega beam, and after considering elastic deformation of subgrade, the simplified model, named space-pole-storey model, is used to dynamic analysis. Consequantly a reasonable and feasible simplified method for dynamic analysis of space mega frames on elastic subgrade is presented.关键词
