摘要 针对预应力碳纤维布加固二次受力钢筋混凝土梁的受力性能,利用有限元分析软件ANSYS,进行了非线性数值模拟,分析结果与试验结果吻合较好,证明所建立的三维有限元模型是有效的。利用该正确的模型,分析了混凝土强度等级、钢筋配筋率、碳纤维布预应力、碳纤维布加固量、持荷大小等因素对构件受力性能的影响,为工程设计提供参考依据。 The finite element analysis software ANSYS is used to do the nonlinear numerical simulation in order to investigate the mechanical behavior of secondary loaded concrete beams which reinforced by pre-tensioned CFRP. The analysis results are in good agreement with experiment results and show that the established 3D finite element model is effective. The effect of concrete strength, reinforcement ratio, CFRP amount of pre-tensioned reinforcement, carbon fiber cloth, holding load size and other factors on the performance of the force is analyzed with the correct model, and the result provides a reference basis for engineering design.
