中文摘要：

为了研究FRP筋混凝土梁面板的承载能力，采用了大型商用软件ABAQUS对Sherif EI—Gamal等的钢混桥梁模型进行了数值模拟。将非线性有限元计算结果同试验结果进行对比分析，非线性有限元的计算结果与试验结果吻合良好。基于数值模准确的分析结果，对结构体系中的压缩薄膜效应进行了分析，并开展了一系列的参数学习，包括混凝土强度、支撑梁刚度以及横隔梁。分析结果表明，压缩薄膜效应对FRP筋混凝土桥面板的承载能力有显著的影响。

英文摘要：

In the investigation of ultimate strengths in FRP reinforced concrete bridge deck slabs, a commercial software named ABAQUS was used to establish the numerical model for steel-concrete composite bridge tests by Sheriff EI-Gamal et al. In the comparison of nonlinear finite element analysis and experimental tests, numerical re- sults showed good accordance with those from experimental tests. According to the accurate validation, the analysis of compressive membrane action in this structural type were developed with a series of parametric study, including of concrete compressive strength, supporting beam stiffness and diaphragm beams. It was found that influence from compressive membrane action on loading capacities in FRP reinforced concrete bridge deck slabs was significant.
