摘要:
采用有限元程序ABAQUS,对碳纤维增强复合材料(CFRP)筋复合增强板加固石梁的受弯性能进行数值建模.利用已有的荷载-挠度曲线、荷载-CFRP筋应变曲线数据对建立的模型进行可靠性验证,结果表明:有限元模拟结果和试验结果吻合良好.在此基础上,对加固后的石梁进行受力全过程截面应力分析,归纳得出荷载-变形特征曲线.基于平截面假定,提出采用CFRP筋复合增强板加固石梁的受弯承载力计算公式,计算得出的开裂弯矩与试验结果和有限元模拟结果吻合较好.
Abstract:
Using finite element program ABAQUS, the numerical modeling of flexural behavior of stone beams strengthened with prefabricated carbon fiber reinforced polymer(CFRP)-reinforced stone sheets is carried out. The reliability of the model is verified by the existing data of load-deflection curves and load-CFRP strain curves. The results show that: the finite element simulation results are in good agreement with the experimental results. On this basis, the cross-section stress analysis of the strengthened stone beam is carried out in the whole process, the load-deformation characteristic curve is summarized. Based on the plane section assumption, a formula calculating the flexural bearing capacity of stone beams strengthened with prefabricated CFRP-reinforced stone sheets is proposed. The calculated cracking moment is in good agreement with the experimental results and the finite element simulation results.
