Three-Dimensional Analysis of the Partner of Laterally Loaded Variable Rigidity Pile (Pile Partner)
Concerning the stress and displacement of the partner under lateral load, reference on full-scale model tests on behavior of cast-in-place concrete pipe piles, two cases are analyzed by means of 3D finite element method, calculations show that in condition I, pile and cap rigid joint (pile foundation) plus partner, partner block the punching stress from pile top to cap continue to spread; and in condition II, the distance between pile top and pile cap is 200 mm, partner is in normal bending shear state; As the flexural rigidity of partner is much larger than the pile, if under earthquake or other rare action, partner may sacrifice firstly to keep pile perform well.
