某桁架结构与地基基础共同作用分析

Analysis on mutual action between truss structure and foundation base

针对某些情况下,地基变形会对结构内力产生较大影响的情况,通过对某一桁架结构的分析表明,在地基变形较不均匀时,忽略结构与地基基础共同作用会导致结构不安全,以指导相关设计人员注意这一影响。

In light of great impacts of foundation deformation on structural internal force, through analyzing some truss structure, it proves that neglecting mutual action between structure and foundation base can lead to unsafe structure under the condition of uneven foundation deformation, with a view to cause designer＇ s attention.
