铁路钢混凝土组合桁架外接式节点力学特性研究
Research on Mechanical Characteristics of Steel-Concrete Composite Truss Joints Railway Bridge
摘要
Abstract
With reference to the 1-80 m Xi'an-to-Pingliang Railway composite truss engineering project and based on the external-nonlinear analysis of steel-concrete composite nodes, load tests are conducted on specimens of the node according to the analysis result. Using the method of mutual authentication of theoretical calculation and experiment, in-depth studies are carried out on external nodes bearing capacity, failure mode and other mechanical properties. Analysis results show that such type of steel-concrete composite joints are qualified to meet the requirements of the project; theoretical calculation results agree well with the experimental findings, theoretical calculations can be used to guide the design, and calculation results meet the strict requirements of the project.关键词
