UHPC-钢组合桥面板结构设计分析

Structural Design and Analysis of UHPC-steel Composite Bridge Deck

以某全互通立交为工程背景,匝道曲线段采用钢-UHPC组合连续梁结构,通过MIDAS有限元仿真计算分析了UHPC-钢组合桥面板在车辆荷载作用下的受力性能,对比了不同加劲肋对组合桥面板第二体系应力的影响,得到了一些有价值的结论,可以为类似结构设计提供参考。

Taking an interchange as the engineering background,the curve section of ramp is the steel-UHPC composite continuous beam structure.The mechanical performance of UHPC-steel composite bridge deck under vehicle load is analyzed by MIDAS finite element software.The influences of different stiffening ribs on the second system stress of composite bridge deck are compared.Some obtained valuable conclusions can provide the reference for the design of similar structures.
