DESIGN AND CONSTRUCTION OF 24 m-LONG-SPAN LATTICE SRC TRANSFER STRUCTURE
-
摘要: 某24 m跨转换结构采用了格构式钢骨混凝土转换梁,介绍了该转换梁的设计与施工要点。为保证节点的工作性能,采取梁端加腋和设置节点加强桁架的构造措施,并提出了格构式钢骨混凝土节点抗剪强度计算公式及转动刚度分析方法。采用的设计思路和施工措施可供类似工程参考。

Abstract: The lattice SRC structure is used in some 24 m-span transfer structure in one building.This paper introduces the key points of its design and construction.To satisfy working performance of joints,the haunched beam and the reinforced truss at joints are applied properly,meanwhile the formula for shear strength and the analysis of rotational stiffness are presented in detail.The design idea and construction measures may be a reference for similar structures.-
