Abstract: In order to solve the problems of poor accuracy and low accuracy in the calculation of the compressive strength and elastic modulus of building concrete, this paper presents a simulation study of the compressive strength and elastic modulus of concrete under multi-axial stress. By constructing concrete feedforward neural network structure, the overall quality of concrete compressive strength is improved. The single hidden layer feedforward neural network is used to calculate the elastic modulus of concrete. The concrete multiaxial model is built to simulate the compressive strength and elastic modulus of concrete under multiaxial stress. In order to verify the accuracy of the prediction method of concrete compressive strength, a comparative test was designed to verify it. The results show that the method presented in this paper can effectively improve the prediction accuracy of the compressive strength of building concrete and the calculation accuracy of the elastic modulus of concrete.
