This study describes a prediction model for the impact vibration of raised access floors by a Finite Element Method (FEM) numerical analysis. The residual ratio of the natural frequency of the peak wave is 1.3% and the residual ratio of the maximum vibration acceleration is 0.8%, which indicates the accuracy in application of the numerical model. With the validated numerical model, this study evaluates the influence on the vibration of various construction parameters. It is shown that the panel material, bracing, and panel thickness may reduce the impact vibration.
