Comparison of Initial and Improved Hertz-Damp Model for Structural Pounding Simulation

Abstract:

In order to compare the initial and improved Hertz-damp model, the dynamic equations of collision system were established based on Hertz-damp model and mode superposition method. Hertz-damp model can account for the influence of the nonlinear contact stiffness as well as the energy loss during structural pounding. The results analysis show that the initial model have the same simulation results with the improved model initial model when the restitution coefficient or the contact stiffness large enough. For typical concrete structural pounding, the initial model is available.
