Abstract

<p>This paper analyzes the factors in the shear fracture behavior of reinforced concrete beams using numerical simulation based on experimental design. The non-linear finite element analysis with a damage model is applied to the fracture simulation of reinforced concrete beams. The shear fracture behavior, similar to the experimental results, is simulated by the numerical experiments with an orthogonal array. The influential factors in the shear fracture behavior of reinforced concrete are quantitatively analyzed by the analysis of variance and the response surface methodology. The results reveal that the material strength of concrete strongly influences the shear fracture behavior of reinforced concrete beams.</p>
