Abstract
The plastic behavior of exterior beam-column joint with different fiber reinforced concrete (FRC) is explored experimentally under cyclic loading. Steel fiber and polypropylene fibers are used in fiber reinforced concrete and engineered cementitious composites respectively. A total of four specimens were prepared, among the four two specimens are conventional and remaining two are with different FRC. The hysteresis loop, stiffness degradation, energy dissipation and damage index are the considered parameters to quantify the plastic response of employed technique. The quantification of results shows enhanced load carrying capacity and energy dissipation capacity with lesser rate of stiffness degradation. The post failure analysis authenticates that the use of fiber improves the damage tolerance behavior and ductility enhancement without sudden loss in strength.
