Dynamic response of pavement under FWD using spectral element method
Abstract This paper presents the development of Spectral Element Method (SEM) for simulating pavement response under FWD pulse loads. Based on Fourier-Bessel function and Fast Fourier Transform, the algorithms and procedures of SEM are introduced, including the formation of layered stiffness matrix and system stiffness matrix with different bond conditions between two interfaces. Deflections calculated from the SEM under different pulse durations are compared and verified with static deflections calculated from BISAR3 and measured dynamic deflections separately. Research results indicate that pavement deflections are sensitive to load pulse duration. The SEM can also be used to solve viscoelastic problems by choosing proper rheological models.
