In this paper, through ANSYS finite element simulation analysis, the effects of initial cracks, mid-span bending moment and deflection of different grades of basic magnesium sulfate cement concrete beams are studied. The research results show that as the grade of basic magnesium sulfate cement concrete increases, the mid-span bending moment during initial cracking gradually increases overall, while the bending stiffness increases while the deflection decreases. As the grade of basic magnesium sulfate cement concrete increases, the mid-span bending moment at yield gradually increases, and the mid-span deflection decreases gradually. Research shows that basic magnesium sulfate cement concrete has good toughness and strength, and can effectively improve the bending performance of its beam members.
