1 -g shaking table tests were performed in order to study the seismic behavior of laterally braced sheet pile walls retaining cohesionless soil. The dynamic pressures, backfill accelerations and wall displacements were measured on a 65 cm high model wall under input accelerations ranging between 0.06g and 0.3 8g. The 3 mm thick wall was fixed at three levels. Data acquisiton components consisting of dynamic pressure transducers, accelerometers, displacement transducers, signal conditioning board and a data acquisiton card were used throughout the study. Incremental dynamic pressures and corresponding lateral thrusts, point of application of the resultant, dynamic and permanent wall deflections, residual pressures, backfill acceleration amplifications were calculated from the stored data. Surface settlements at the soil-wall interface were also recorded. Effect of number of cycles on the lateral thrust and point of application of the resultant were investigated. The results were compared to the available analytical methods and other model experiments.
