• Abstract:

  Since reinforced concrete beams present nonlinear and complex characteristics in terms of structure, the analysis of their flexural performance may result in poor accuracy due to the lack of effective analysis of the constitutive relationship. In this regard, the finite element simulation analysis of the flexural performance of reinforced concrete beams is proposed. Firstly, according to the actual size and design requirements of the concrete beam, the basic parameters of the model are set, and seed points are arranged in the key areas or boundaries of the geometrical model to guide the generation of the mesh, so as to construct the finite element model. Then the choice of combining the stress-strain curve is made to calculate the concrete principal relationship. By combining the quadratic flow-plastic simplified model, the stress-strain relationship of concrete is simplified into a nonlinear form, and the flexural performance parameters, such as yield strength and shear strength, are solved by combining the segmentation function. Finally, the actual analysis effect of the method is verified by constructing an experimental comparison link. Through the visual analysis of the results, it is clear that the yield load fitting degree of concrete beams by this analysis method is obviously high and has ideal analysis accuracy.
