An Experimental Study on the Crack and Fracture Behavior of FRC Column

This paper describes an experimental study on the crack and fracture behavior of the FRC column. The test were carried out as Fiber contents in the Steel Fiber Reinforced Concrete and addition of Polypropylene Fiber in PFRC for evaluate the ability of ductility. In this study, the width and size of crack reduced remarkably and the progress of cracks were restrained by the steel fiber contents increasing, and in the case of PFRC the occurrence of initial crack reduced conspicuously. Accordingly, the addition of steel fiber in Reinforced Concrete Columns considerably prevent an unexpected buckle and rupture, secure durability and stability of columns.
