Abstract

Recently, TYFO glassfibers have been used for strengthening n aged RC bridge slabs because of low material cost and easy repairing work. The purpose of this study is to experimentally and analytically investigate the effect of TYFO glassfibers for enhancing the capacity of aged RC bridge slabs. Tes result shows that yield and ultimate strength of RC slabs with TYFO are increased as 11~18% and 25~35% comparing with those for RC slabs without TYFO, respectively, Also, ductility of RC slabs strengthened with TYFO have been significantly increased. Further tests have been performing on aged RC bridge slabs strengthened with carbon fiber strips.
