Abstract

In this paper, applications of the frequency dependent damping to time domain analysis are presented with the use of Fourier transform. The proposed transformed damping models are compared with conventional models simulating vertical excitations of a SDOF lump-mass system. The result implies that the transformed models is similar to the conventional models under steady-state loads. Modeling of the damping ratio is very important for the model simulating structural response under an impact. Pile response due to axial loads can be qualitatively achieved by solving the wave equation with these models and the finite difference method. 1 Introduction Damping mechanism which dissipates the energy as the velocity of motion and strain varied is important to dynamic analyses in solid me
