MULTI-DIRECTIONAL SEISMIC RESPONSES OF HYBRID TEE WALLS

Seismic response analyses were performed on 10- and 20-m hybrid cantilever retaining walls (HTW) with RC cantilever stem and mechanically stabilized earth (MSE). Geogrid is used as the reinforcement and is either attached or detached to the RC wall. The analysis uses the Imperial Valley Earthquake ground motion and its scaled motions to examine the effect of severity of earthquake-induced ground shaking on HTW seismic responses. Wall height, ground motion intensity, multi-directional shaking, and inclusion connection conditions were found to significantly affect the wall displacement and rotation, inclusion stresses, earth pressures, and bearing pressure of HTW. The earth pressure with multi-directional shaking differs from the AASHTO's Mononobe-Okabe (M-O) prediction.
