The Effect of Core Filling on Seismic Performance of Pretensioned Centrifugal Spun Concrete Piles with Steel Strands
Pretensioned centrifugal spun concrete piles with steel strands have been developed to improve the seismic performance of precast-prestressed concrete hollow piles. In this paper, two pile specimens with reinforced concrete infilling were fabricated, and lateral cyclic loading tests were conducted. A finite element model is developed to predict the hysteretic characteristics of core-filled pile specimens. The results show that reinforced concrete infilling improves the cracking pattern and failure mode of piles. Core-filled piles exhibit better structural stability and higher deformability than hollow piles. Reinforced concrete infilling enhances the lateral load-carrying capacity and deformability more significantly than plain concrete infilling.
