There is confusion among civil engineers in the United States regarding the applicable design method and the appropriate impact load for sizing the moment slab of roadside barrier systems atop MSE retaining walls. The design method and impact load discussed herein have been used successfully for more than 15 years to size the barrier moment slab and to determine the magnitude of loads applied t...

Few studies have been conducted on polymeric strip and the behavior of soil retaining walls. This paper will present the effect of frequency on the dynamic behavior of reinforced soil retaining walls with polymeric strips. The frequency content describes how the amplitude of a ground motion is distributed among different frequencies. Since the frequency content of an earthquake motion will stro...

Present scenario of the engineering practice is indulged in the search of highly developed methods to judge the earth's retaining walls under seismic conditions which are mostly empirical and based on experience rather than the theories. Understanding the nature of earth retaining structures in unstable events caused by natural phenomena is one of the oldest problems in geotechnical engineering...
