Abstract

Abstract

In order to study the mechanical properties of earthquake-resilient box-shaped steel piers, the numerical analysis of the new box-shaped steel piers was carried out under axial tension and compression by ANSYS software. The axial compression tests and numerical simulation results of the new box-shaped steel piers were compared to verify the reliability of the finite element simulation method. On this basis, the influences of the height, width and thickness of the low-yield point energy-consuming steel plates on the skeleton curves, ductility coefficient and energy dissipation capacity of the new box-shaped steel piers were discussed. The results showed that the width and thickness of the steel plates with low-yield point had a great influence on the bearing capacity of the box-shaped steel piers. The bearing capacity of the specimens decreased with the increase of the width of the steel plates with low yield point, and increased with the increase of the thickness. The height of the low-yield point steel plates had little effect on the bearing capacity of the new box-shaped steel piers. If the height of the steel plates with low-yield point increased in the range of 1/3~5/7 times of the specimen, the energy dissipation capacity of the box-shaped steel piers would be improved. While the thickness of the steel plates with low-yield point increased in the range of 1~1.5 times the thickness of the web plates, the energy dissipation capacity of the box-shaped steel piers would also be improved. When the width of the steel plates with low-yield point increased, the energy dissipation capacity of the box-shaped steel piers decreased.
