ARSA method is a displacement controlled pushover analysis method. In the method, the modal displacement increments are scaled according to the nonlinear spectral displacement value obtained according to the instantaneous dynamic characteristics of the structure. In the previous step, in order to find the modal scaling value in each nth vibration mode, the elastic spectral displacement of the system, the value from S (1), was found by using the equidistant displacement rule.

The cumulative spectrum scale coefficient calculated at the end of each i th thrust step, It is checked whether it exceeds the unit value with the highest value. If it does not exceed, the analysis continues.
