Paper Title:
Effects of Matrix Ductility on Damage Tolerance of Diagonally Reinforced Coupling Beams
  Abstract

This paper investigates the effect of the ductile deformation behavior of high performance hybrid fiber-reinforced cement-based composites (HPHFRCCs) on the shear behavior and damage of diagonally reinforced coupling beams under reversed cyclic loading. The effects of matrix ductility on deflections, crack widths, crack patterns, failure modes, and ultimate shear load of the coupling beams have been examined. The combination of a ductile cement-based matrix and steel reinforcement is found to result in improved energy dissipation capacity and damage-tolerant inelastic deformation behavior. Test results showed that the coupling beam constructed with an HPHFRCC material exhibited excellent strength, deformation capacity, and damage tolerance capacity, in comparison with the regular reinforced concrete beam.
