| 摘 要： | 对拉挤成型GFRP桥面板各项宏观力学性能进行分析,探讨将其等效为总体正交异性板的各个等效力学参数的取值,并通过有限元数值模拟对等效方法进行验证。对于GFRP组合桥面系统,通过对不同边界条件进行分析,确定了其计算模式。最后,提出刚度控制设计时拉挤成型GFRP组合桥面在横GFRP简支组合梁桥轴线方向上的设计挠度标准及此类桥面系统的设计方法。 |

| Abstract: | This paper analyzes various macro mechanical properties of the pultruded GFRP composite deck slab,discusses the values of each equivalent mechanical parameter of the deck slab that has been equalized as a generally orthotropic slab and verifies the method for equalizing the slab by finite element numerical simulation.For the GFRP composite deck system,the paper further determines its computation modes on the basis of analysis of different boundary conditions and finally,proposes the design deflection criterion for the pultruded GFRP composite deck transverse to the axis of the simply-supported GRFP composite girder bridge when the rigidity control design is applied and also the design method for the type of the composite deck system. |
