Abstract

Three L-shaped columns with HRB500 reinforcement were tested under low cyclic loading. The effect of stirrup ratios on damage characteristic, hysteretic characteristic, rigidity degradation and energy dissipation capacity was analyzed to research the hysteretic behavior of L-shaped columns with HRB500 reinforcement. The result shows that the damage characteristic and the hysteretic characteristic of L-shaped columns with HRB500 reinforcement are improved with the increase of stirrup ratios. The energy dissipation capacity of L-shaped column was also enhanced after ultimate load with the increase of stirrup ratios.
