This experiment compares data from the live Webshaker experiment to the result of the Two Degree of Freedom (2DOF) equation computer program.
The base acceleration recorded from the live Webshaker experiment is used as input motion to the 2DOF experiment program.

You can view the Fortran code of the 2DOF Computer Program .

Please choose one of the following for your comparison experiment:

1. Sinusoidal Input: to use a sinusoidal wave as input to the shaker
2. Earthquake-like Records Input: to use earthquake-like base acceleration records as input to the shaker.
