Abstract

Abstract

In order to study the seismic performance of centrifugal concrete-filled steel tubular piles (SC tube piles) and consider the influence of core filling and prestress, the quasi-static tests were carried out on 3 SC tubular piles and 2 prestressed high-strength concrete tubular piles (PHC tube piles). The results showed that the seismic bearing capacity, yield displacement, ultimate displacement and ductility coefficient of SC tubular piles were 2.85 times, 1.97 times, 2.47 times and 1.47 times of PHC tubular piles, respectively, the energy consumption coefficient was about 4.5 times of PHC tubular piles, and the total energy consumption was 32 times of PHC tubular piles, the cut line stiffness of SC tubular piles in the same displacement conditions was about 2-3 times that of PHC tubular piles, and the displacement of SC tubular piles when the bearing capacity dropped steeply was about 2.4 times that of PHC tubular piles; the seismic bearing capacity of prestressed SC tubular piles was about 15% higher than that of SC tubular piles; the effect of concrete filling on the seismic performance of SC tubular piles was negligible.
