本文结合某特大桥梁的临时施工支架设计,设计了基于军用梁组装的临时支架体系。该体系采用大型通用有限元程序,建立三维杆系分析模型。考虑实际工程中的荷载模式,对主要受力杆件进行了计算分析,评价了其强度和刚度在施工荷载作用下的结果。最后根据计算结果,提出结论。 Based on the design of temporary construction support for a large bridge, this paper designs a temporary support system based on military beam assembly. The system uses a large common finite element program, the establishment of three-dimensional bar analysis model. Considering the load model in the actual project, the main force components were calculated and analyzed, and the result of the strength and stiffness under construction load was evaluated. Finally, based on the calculation results, the conclusion is reached.
