摘要：

In order to solve the problem that the numerical simulation results of the bearing capacity of the reinforced concrete high pressure members are not accurate, the numerical simulation research of the bearing capacity of the reinforced concrete high-pressure members is put forward. The additional stress of concrete members is calculated by elastic theory formula, and the longitudinal equilibrium differential value of concrete members is obtained. The additional stress of the compression member is calculated. In order to meet the requirements of calculation time and simulation precision, the reinforced concrete members are discretised by grid partitioned. The results show that the relative error of the root mean square value of this method is 0.10, the accuracy is 98%, and the reliability is 99%. This method can effectively overcome the high-pressure bearing capacity of numerical simulation of reinforced concrete members, and can measure the principal tensile stress limit value of fixed end concrete members. The finite element simulation results are close to the experimental values. Copyright © 2022 Inderscience Enterprises Ltd.
