Abstract: Engineered cementitious composite (ECC) is a type of high performance fiber reinforced concrete (FRC) with some good strain hardening behavior. This study deals with use of two different fibers, polyvinyl alcohol (PVA) and polypropylene (PP) fiber.PVA fiber is better than PP in terms of mechanical property. A total of 5 columns are prepared, one each of ECC with PVA fiber PVA(R/ECC), ECC with PP fiber PP(R/ECC), and one reinforced cement concrete (RC) column for comparisons. Rest of the two column deals with effective use of ECC in tension zone of the column PVA(R/ECC-RC) and PP(R/ECC-RC) i.e.in the top and the bottom (L/4) region, ECC is used and the centre (L/2) region is filled with RC. Same longitudinal reinforcement ratio was adopted for all the columns and columns were tested under eccentric compression. Due to eccentric compression RC column went through scaling and spalling process while this was not found in ECC columns due to fiber binding effect with cementitious material .Further more columns were analysed using finite element software ABAQUS to plot, Load versus Deformation curve, yielding pattern and stress distribution in the column .
