摘要
以三等跨简支平台桥梁加固为例,提出钢结构拱形桁架的桥梁加固改造方法。通过有限元结构分析软件,分析钢结构在各种工况组合下结构的受力性能,保证了结构的安全可靠,满足了拱形钢架的强度、刚度和整体稳定要求,合理控制了钢架变形,满足了工程实际需要。
Strengthening of trisected simply-supported platform bridge is taken as an example to give out the strengthening and rebuilding methods for bridge with steel structure arch truss. Finite element structural analysis software is used to analyze the force bearing performance of steel structure under various service conditions, so as to strength, rigidity and guarantee the safety and reliability of steel structure, to satisfy the requirements for stability of arch steel frame, to reasonably control the deformation of steel frame and to meet the practical engineering requirements.
