钢结构转换桁架在工程中的应用与分析

APPLICATION AND ANALYSIS OF STEEL TRANSFER TRUSSES IN ENGINEERING

实际工程设计中,经常会遇到建筑底层抽柱形成大空间的建筑功能要求。介绍一个为满足底层抽柱采用钢结构转换桁架的结构设计实例。重点介绍结构体系的合理选择,结构整体设计,钢结构转换桁架的设计与分析,转换桁架特殊节点的设计与有限元分析。结果显示,通过合理巧妙地布置结构构件,可满足建筑功能使用要求,并使结构整体具有良好的工作性能。研究成果对该类结构在工程设计中的应用与推广具有一定指导和借鉴意义。

In practical engineering design, it is very common to remove columns from ground floor for a large space. A structure which can meet the requirements of removing columns ground floor through using steel transfer truss was described in this paper. It was focused on reasonable selection of structural system, the overall design of the structure, design and analysis of steel transfer truss, transfer truss design and finite element analysis of special joints. The analysis results showed that reasonable arrangement of structural elements can meet the needs of functional requirements of the building and excellent overall performance of structure. The obtained research results would provide an important reference for the application and promotion of such structure in engineering design.
