Abstract

Abstract

PHC pipe pile has been widely used in foundation engineering due to its high seismic performance and large bearing capacity of single pile. The uplift resistance of pile-pile joints is one of the key issues to be considered when connecting piles. ABAQUS finite element software was used to establish the calculation model of the hooped joint of PHC pipe pile, and the mechanical mechanism of the joint was studied. The effects of the edge width, radial thickness and plate thickness on the stress distribution and the tensile capacity of hooped pile were investigated. The calculation results showed that the size of the U-shaped hoop had a certain influence on the failure mode of the joint under tension. When the load reaches the design load, the model’s maximum stress of the hoop, plate and prestressed reinforcement decreased with the increase of hoop size. With the increase of plate thickness, the maximum stress of hooped clamp and end plate decreased, while the maximum stress of prestressed tendon increased.
