BEHAVIOR OF NARROW MECHANICALLY STABILIZED EARTH WALLS UNDER EARTHQUAKE LOADING
Ahmed Saad Rabei Mahmoud;
Abstract
Summary
The construction of Narrow Mechanically Stabilized Earth Walls (NMSE) of aspect ratio (ratio of reinforcement length, L, to wall height, H) below 0.70 is expanded, recently, in urban areas in limited space. When NMSE walls constructed in active seismically zone, these walls are subjected to seismic ground motion. A Series of 11 shaking table tests are performed on reduced scale NMSE wall model (1/8 of the prototype model) considering the ground motion characteristics, wall aspect ratios, facing rigidity and wall configuration. The modelled walls display that NMSE walls behave as rigid body until yield occurs at input base acceleration ranging for 0.15g to 0.44g and these accelerations is the critical accelerations which corresponding to 0.5 % top wall displacement ratio.
