Abstract
In this article, the performance of single-column circular concrete bridge piers, using steel materials and shape memory alloys, was examined under the influence of cyclic loads. A set of bridge piers with various height-to-diameter ratios of 0.2, 0.4, and 0.6 was considered under gravity load-to-axial capacity ratios of 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6. A comparison was made between two scenarios: using shape memory alloy and conventional steel as the reinforcing bars for the piers. The analysis of the piers was conducted based on their lateral displacement in a cyclic manner, and the reactions at their supports were recorded. According to the results obtained, it was observed that the maximum shear capacity of the bridge piers increases with an increase in the height-to-diameter ratio. Furthermore, by employing reinforcement made from shape memory alloys, the maximum shear capacity of the piers decreases by 5% to 15% compared to a similar model with steel reinforcement. Additionally, using reinforcement made from shape memory alloys enhances the ductility capacity of the bridge piers, and the normalized hysteresis energy is a function of the diameter and the intensity of the gravity load applied to the piers. The use of reinforcement made from shape memory alloys resulted in a reduction of 30% to 80% in the amount of normalized hysteresis energy of the piers.
