Abstract
An attempt was made in this paper to use waste tire shredded rubber (WTSR) fiber as a damping material back paneled to the Cantilever Retaining (CR) wall. WTSR fibers placed to absorb seismic-induced thrust on CR wall effectively, thus resulting in reduction of lateral displacement. A series of tests on models of cantilever retaining wall were conducted on uniaxial shaking table. A displacement of 10 mm in z-direction and frequencies of 5, 10, 15, and 20 Hz were selected for all the configurations of fiber panel widths. Four configurations were chosen based on fiber panel width, back to the CR wall which, are 0, 50, 75, and 100 mm. The deflections of the wall, with respect to frequency were measured. It is observed that inclusion of WTSR fiber effectively adsorbed the dynamic trust acting on the CR wall.
