摘要：In this study, attempts were made to modify the C-Park-Ang damage model for its applicability to PHC pipe pile embedded in clay soil. According to the fibre beam element theory and the common node method, the finite element (FE) model of PHC pipe piles considering pile-soil interaction was established by the ABAQUS/Standard software program. The non-linear FE analysis was then performed to study the effect of length-diameter (l _eq/D) ratio, axial compression ratio n ₀ and configuration of transverse and longitudinal reinforcement on the energy combination coefficient β _c of damage model through monotonic and reversed cyclic lateral loading. The modified equation of energy combination coefficient β _cm of PHC pipe pile is obtained by non-linear regression and the modified seismic damage model of PHC pipe pile is proposed.
