[Retracted] Stress Analysis of Concrete Materials Based on Finite Element Analysis

Table 4

Main reasons for the deviation of the test simulation.

1	When the FEA model was established with ABAQUS software, it was assumed that the bond between the reinforcement and concrete was good, and there was no slippage between the reinforcement and concrete before the specimen reached the ultimate bearing capacity, so there was a certain difference between the actual test force and the FEA simulation value and the test value of the reference literature.
2	We use ABAQUS software to simulate the FEA model, and the material’s intrinsic structure relationship is applied to the FEA by reviewing other data and doing a lot of experiments with instrumental data, so the intrinsic structure relationship of the FEA simulation may be inaccurate with the experimental intrinsic structure data of the reference literature.
3	The determination of the cube compressive strength of concrete in the test is obtained under more ideal conditions, while in the actual test, there is a certain degree of error in the production of concrete cube specimens, and there may also be a certain degree of human error in the collection and collation of test data, which leads to a certain difference between the data obtained from the ABAQUS finite element simulation and the data from the reference literature.
