摘要
钢-混凝土连续梁桥作为一种新型的组合结构,将主跨部分梁段采用钢结构代替传统的混凝土结构,以达到降低桥梁结构自重,增大跨越能力,改善结构的受力性能。在钢-混连续梁中钢混结合段为该结构的关键点。以某钢-混凝土连续梁桥为背景,对钢混结合段建立空间有限元模型进行局部应力分析,并结合对该桥荷载试验的检测结果,分析钢混结合段的受力情况,评价其技术状况。
As a new composite structure, the partial beam section of the main span in the steel-concrete continuous beam bridge is the steel structure to replace the traditional concrete structure in order to reduce the dead load of bridge structure, to increase the spanning capacity and to improve the stress performance of structure. The steel-concrete composite section is the key point in the steel-concrete continuous beam. Taking a steel-concrete continuous beam bridge as the background, this paper establishes the spatial finite element model of the steel-concrete composite section to carry out the local stress analysis, and combined with the detection result of load test of this bridge, analyzes the stress situation of steel-concrete composite section and evaluates its technical conditions.
