Abstract
This study, tries to suggest a design method based on displacement using finite difference numerical modeling in reinforcing soil retaining wall. In this case, loading characteristics, such as magnitude, frequency, peak ground acceleration and geometrical characteristics of reinforced soil structure are considered to correct the pseudo static method and finally introduce the pseudo static coefficient as a function of seismic performance level and peak ground acceleration. In addition, the authors has tried to simply suggest the equivalent harmonic loading of selected acceleration records. Considering the loading parameters, mechanically stabilized earth wall parameters and type of the site showed that the used method in this study leads to most efficient designs in comparison with other methods which are generally suggested in cods that are usually based on limitequilibrium concept. The outputs shows the over-estimation of equilibrium design methods in comparison with proposed displacement based methods here.
