Experimental study on seismic strengthening scheme of RC pier by aramid fiber rope

Abstract

Recently, seismic retrofit method by continuous fiber for the RC pier is researched to put to practical use. In this work, new seismic retrofit method using aramid fiber rope for RC pier was invesigated in order to build the design method. The loading test was curryed out with the specimen that changed its cross-section shape and pitch of the aramid fiber rope. And we investigated the strengthening effect and its mechanism based on the experimental rusults.
