Experimental analysis of a shake table test of strip footing on two layered reinforced soil

This paper represents both experimental and numerical study of the strip footing resting on two layered reinforced c-. soil. Small scale shake table tests are conducted to evaluate the different parameters like vertical settlement, (Root mean square amplification) RMSA factor, and total stress at different levels of layered soil. Test results revealed that increase in moisture content the parameters like vertical deformation, RMSA are increasing and after the optimum moisture content the above parameters are decreasing. Further addition of moisture content increases the above parameters. Inclusion of reinforcement tends to reduce all the above parameters but is more effective in reduction of maximum RMSA amplification factor. From the numerical result, it is seen that by increasing the moisture content vertical deformation and RMSA factor is increasing by 5-10%. To verify the results obtained from the present study, a numerical analysis is done by using PLAXIS 2D and the acceptability of model is discussed. It is observed the differences between experimental and numerical results are varying from 2-6%.
