Abstract:
To study the mechanical properties of the lifting anchor under combined tension and shear, the failure mode and bearing capacity of lifting anchor under different load angles are systematically analyze through the comparison of test and finite element numerical simulation results. Firstly, 16 concrete specimens with embedded lifting anchor were subjected to testing at eight different load angles. Then the finite element software Abaqus was utilized to simulate the specimens, and the obtained results were compared with the experimental data to verify the accuracy of the finite element simulation of the mechanical properties of the lifting anchor under combined tension and shear, which provides a basis for the stress analysis of the complex lifting state in the future. The results show that with the increase of load angle, the ultimate bearing capacity and tensile-shear coupling stiffness of the lifting anchor increase gradually. The ultimate combined load of the specimen increased by about 41% from 0 degrees to 90 degrees. The mathematical statistics method was applied to fit the test data, and the calculation formula of the load-bearing capacity of the lifting anchor under the combined action of tension and shear is established. The average R-squared value of the calculation formula is 0.95, which is in good agreement with the experimental data and improves the design and evaluation accuracy of this type of structure.
