Performance Evaluation of Geogrid-Confined Beam-Column Joints With Steel Fiber Reinforced Concrete Under Cyclic Loading

CODEN: JTEVAB

Abstract

Cyclic performance of beam-column joint specimens was evaluated under conventional confinement and geogrid confinement with and without steel fiber reinforced concrete (SFRC). The efficacy of these specimens was compared on the basis of hysteresis behavior, load-deformation envelope curve, energy dissipation, strength and stiffness degradation, moment-rotation relationship, and failure pattern with damage index. The test results indicated that the additional geogrid confinement at the joint improved the performance significantly, and the use of SFRC further helped to increase the shear resistance capacity of the joint. The damage index of geogrid-confined specimens was reduced to at least one level lower on the same deformation range as compared to the conventional specimens.
