ABSTRACT
Long-term deformation performance is an important structural feature of concrete bridges, which has a great influence on their engineering practice. Using the ABAQUS finite element simulation method, a numerical analysis model for the creep of steel fiber ceramsite concrete beams was established, and the body surface ratio of the specimen, the steel fiber content, the loading time, and the law of creep development were analyzed. Numerical simulation and test results show that the creep value of steel fiber ceramsite concrete beams shows a decreasing trend with the increase of steel fiber content and body surface ratio of the specimen, and its change rule is also consistent with the test results and the ACI435 creep calculation model. Similarly, the three test errors are all within 5%, and the fitting effect is better, which verifies the accuracy of the numerical analysis method and model.
