Abstract

This paper investigates the effect of rubber-sand-mixture (i.e., rubber–sand mixtures, abbreviated hereafter as RSM) layer on reducing the acceleration response of the foundation. Numerical modeling was performed by using finite difference in two-dimensional-plane strain method. The object of this study is to investigate the sensitivity of the foundation acceleration response to the percentage and dimensions of the RSM layer, which is placed under the foundation in different percentages and dimensions. The ground structure was considered as surcharge in the model and the wave was applied harmonically from the base of the model. As the percentage of rubber increases, the acceleration of the foundation response and the magnification factor decrease in the results. Increasing the depth ratio (ratio of depth of the RSM layer to the loading width) of the RSM layer decreases the amount of foundation acceleration response and magnification factor, this effect is more at first and gradually decreases with the addition of the depth of the RSM layer. Increasing the width of the RSM layer in the width ratio (ratio of the width of the RSM layer to the loading width) greater than 1.5 has little effect on the results.
