夹梁式墙托换结构设计方法研究

Study on Design Method of Wall Underpinning Structure with Beam Clamped

夹梁式墙托换结构是建筑物移位工程中的主要构件,目前缺乏系统的、具体的设计理论。本文结合墙托换体系力学分析和单片墙托换梁模型试验,研究了该结构的受力状态和托换节点的破坏机理,并在此基础上提出该托换结构设计的三个关键环节的具体计算方法,可为类似结构的设计提供参考。

The wall underpinning structure with beam clamped is the uppermost bearing carrier in building＇s integral move,but there was no systematic and specific design theory about it. Through mechanical analyses and model experiment about this kind of structure, authors made a study of its carrying condition and failure mechanism. As a result, the authors propound a specific design method including three key links about design procedure on this structure, and it can give a reference to similar structures.
