Abstract:
A test scheme on seismic behavior of a new batter pile joint was proposed. Hysteretic curve, skeleton curve, ductility coefficient, secant stiffness and dissipation capacity of the batter pile joint were obtained by using nonlinear finite element analysis. The influences of the stirrup ratio of pile cap, strength of concrete, axial load ratio and reinforcement ratio in the core of piles on seismic behavior of the batter pile joint were discussed. Results show that the stirrup ratio of pile cap and strength of concrete are important for the ductility and dissipation capacity of the batter pile joint, axial load ratio is important for the bearing capacity, stiffness, ductility and dissipation capacity of the batter pile joint. Certain reinforcement distribution in the core of piles can improve the ductility and dissipation capacity of the batter pile joint. After exceeding the requirement quantity of reinforcement, the ductility and dissipation capacity of the batter pile joint change a litter through enhancing the reinforcement ratio in the core of piles. The conclusions have important reference value for seismic behavior test of the batter pile joint under low cyclic loading.
