钢结构装配式模块化建筑连接节点研究综述

Summary of research on connection joints of modular steel structure prefabricated building

钢结构装配式模块化建筑是一种新兴的建筑结构体系,具有高度集成化的特点,已成为当下工程领域研究热点。本文基于国内外相关文献资料的调研分析,对模块间连接节点的构造形式(螺栓连接、焊接与栓焊混合连接、预应力连接及自锁式连接)与力学性能进行了系统梳理与总结,指出了目前模块间连接节点研究存在的不足,并对此提出了相关建议,以期为此类建筑的相关设计及工程应用提供参考。

The modular steel structure prefabricated building is a new building structure system,which characterizes high integration and has become a research hotspot in the current engineering field.Based on the investigation and analysis of relevant literature at home and abroad,the structural formats(bolt connection,welding and bolt-welding hybrid connection,prestressed connection and self-locking connection)and mechanical properties of the connection joints between modules,the shortcomings of the current research on the connection joints between modules are pointed out,and relevant suggestions are put forward,so as to provide references for the related design and engineering application of such buildings.
