“…(2) e failure region of specimens (CT- [8][9][10] mainly concentrated between pile and cap after improvement, the pile end has no severe damage, and the horizontal bearing capacity and energy dissipation performance have no significant improvement. (3) e displacement ductility coefficient of CT-10 and CT-9 is bigger than that of CT-7, which shows that the PHC pile reinforced with steel fiber and deformed bars can improve the deformability and flexural bearing capacity of piles, which causes the displacement ductility of connection to be better.…”

“…Kokusho et al [6,7] found that a combination of concrete filled in the hollow part of PHC piles and high-strength spiral hoop was very effective for improving the deformability of PHC piles. Nagae et al [8,9] conducted cyclic test on prestressed reinforced concrete pile (PRC pile) and considered the effect of axial deformed bars and lateral reinforcement on the seismic performance of PRC piles. e test result showed that PRC piles can exhibit stable hysteretic behavior and significant ductility when properly reinforced with axial deformed bars and lateral reinforcement.…”

Four prestressed high-strength concrete pile- (PHC pile-) pile cap connections under low-cycle loading were tested to study the test phenomena, failure modes, hysteretic performance, ductility, and bearing capacity. The PHC piles were reinforced with steel fiber and deformed bars and CFRP. The tests results showed that the connections were damaged by bending. The concrete of the caps were squeezed to be crushed. The concrete of connection was crushed and formed a hinge joint that resulted in the connection rotating unrestricted, and the rotation capacity of connection increased. The PHC pile reinforced with steel fiber and deformed bars can improve the displacement ductility of the connections. The finite element software ABAQUS was used to simulate the nonlinear behavior of pile-cap connections. The prediction agreed relatively well with the experimental results. The stress and strain of specimens were studied. The connections should be designed with enough rotating capacity and make sure the cap will not be damaged by squeezing or prying due to the rotation of pile end.

“…According to the supporting capacity of the general bearing ground [19], the low, medium and high axial force levels selected in testing the three specimens were 0, 0.2 and 0.4 axial force ratio, i.e., P/Afcd, respectively, where P is the applied axial compressive force, A is the pile cross-section area, and fcd is the concrete design compressive strength with a value of 39.9 MPa herein. The corresponding axial loads for the specimens are 0, 1003 kN and 2006 kN, respectively.…”

The main purpose of this paper is to study the seismic performance of prestressed reinforced concrete pile (PRC pile) reinforced with nonprestressed reinforcements. Two prestressed high strength concrete piles (PHC piles) and two PRC piles were tested. The variables studied in this research are the prestressed reinforcements ratio and nonprestressed reinforcements ratio. The piles subjected to low-cycle loading were presented in this paper, including the hysteretic performance, stiffness degradation curves, coefficient of equivalent viscous damping and skeleton-frame curves. It is shown that the failure modes of all specimens are bending damage from the test and PRC piles have good energy-absorbing hysteretic behavior.
