N2 - This paper presents an analytical framework for the horizontal dynamic analysis of a large-diameter pipe pile subjected to combined loadings, in which the pipe pile is simulated by the Timoshenko beam theory. The derived solution allows us to evaluate the effects of both the shear deformations and vertical loads on the horizontal dynamic performance of the pipe pile. The proposed solution provides appropriate estimates of complex impedances of large-diameter pipe piles, unlike the earlier solutions based on the Euler-Bernoulli beam theory for describing the pile behavior, which ignores the shear deformation of the pile. The results indicate that the Euler-Bernoulli theory overestimates the pipe pile's horizontal impedance, while overestimating the effect of vertical loads on its horizontal performance.
