核心筒伸臂桁架技术研究与应用

Research and Application of Core Tube Extension Arm Truss Technology

伸臂桁架是指在钢构建筑中,采用钢管或钢板进行连接,形成桁架的结构形式。伸臂桁架因其结构合理、强度高、耐久性强等特点,广泛应用于建筑工程中。随着城市化的加速发展,越来越多的超高层建筑在建设中出现。由于超高层建筑高度巨大,面积广大,所需的结构材料和力学性能都比普通建筑更高。而伸臂桁架因其优异的力学性能和结构特点,成为超高层建筑中广泛应用的结构形式。论文依托湖北金控大厦项目核心筒避难层伸臂桁架施工的介绍,浅述对核心筒伸臂桁架技术研究与应用。

Extension arm truss refers to the structural form of a truss formed by connecting steel pipes or steel plates in steel structures.The extension arm truss is widely used in construction engineering due to its reasonable structure,high strength,and strong durability.With the accelerated development of urbanization,more and more super high-rise buildings are appearing in construction.Due to the huge height and vast area of super high-rise buildings,the required structural materials and mechanical properties are higher than ordinary buildings.And the extension arm truss has become a widely used structural form in super high-rise buildings due to its excellent mechanical properties and structural characteristics.This paper is based on the introduction of the construction of the extended arm truss for the core tube refuge layer of the Hubei Financial Control Building project,and briefly discusses the research and application of the extended arm truss technology for the core tube.
