Abstract

In order to investigate improvement in ductility of Reinforced Concrete (RC) piers due to mixing Poly-Vinyl Alcohol (PVA) short-fiber, lateral cyclic loading tests of RC piers were conducted taking with/without stirrup and fiber mixing volume ratio <i>V<sub>f</sub></i> as variables. In this study, normal concrete and PVA short-fiber mixed concrete with <i>V<sub>f</sub></i>= 1, 2, and 3 % were used. From this study, following results were obtained: 1) ductility of RC piers can be improved due to mixing PVA short-fiber in spite of with/without using stirrups; 2) stirrup and PVA short-fiber can be independently affected to improve in ductility of RC piers; and 3) the ductility of the RC piers may closely relate to a shear-bending capacity ratio at the basement of the pier mixed PVA short-fiber.
