Proportion of High-strength Steel Bars in Reinforced Concrete Ductile Piers

This paper mainly focuses on the affect factors of ductility of reinforced concrete pier with the high-strength longitudinal reinforcement and stirrups. By finite element software ANSYS, changed the amount of longitudinal reinforcement and high-strength stirrups in the piers, the ductility performance of concrete piers was studied. The results show that under certain conditions, the ductility coefficient of concrete piers with high-strength reinforcement can increase with the amount of stirrups. In addition, high-strength longitudinal reinforcement can improve the ductility performance of the concrete piers, but it should be controlled in a reasonable range. If there are too much high-strength longitudinal reinforcement in the concrete piers, the ductility performance will be lower, and structural seismic performance will also be affected.
