为了研究FRP筋混凝土板的冲切承载力,采用大型商用软件ABAQUS对Carlos E等的试验模型进行了数值计算,非线性有限元的计算结果与实验结果有着良好的吻合。在准确校正试验结果的基础上,对影响冲切效应的参数进行了分析,包括混凝土强度、加载面形状和板厚。根据参数分析的结果,对FRP筋混凝土板的冲切承载力公式进行修正。通过比较分析,计算结果和有限元解与试验结果非常的接近。

In the investigation of ultimate strengths in FRP reinforced concrete slabs, a type of commercial software named ABAQUS was used to establish the numerical model for slabs tests by Carlos E et al. In the comparison of nonlinear finite element analysis and experimental tests, numerical resuhs showed a good collection with those from experimental tests. According to the accurate validation, a parametric study of this structure was conducted, including concrete compressive strength, loading area and slab depth. According to the analytical resuhs, this paper proposed a modified theoretical prediction methods for ultimate strengths in FRP reinforced concrete slabs. The results from theoretical prediction methods showed a good collection with NLFEA results and experiment result.
