Investigation of the contribution of the reinforcement tie to the seismic behavior of reinforced-concrete columns

Abstract

In seismic design codes it is obligatory to use special earthquake reinforcement ties in reinforced-concrete structural columns. Lack of special earthquake reinforcement ties or any deficiency in arrangement or amount of these reinforcements can cause different levels of damage to the reinforced-concrete structural elements after the earthquake. Within the scope of this study, a total of eight different structural models were created in order to determine the effect of the reinforcement-ties on the shear capacity of reinforcedconcrete columns, considering four different reinforcement-tie models and two different reinforcement materials. The period, seismic capacity and target displacement values were obtained for each structural model. In addition, demand, limit and capacity values for shear force were obtained and compared. Significant contribution to the seismic behaviour of the structure with use of reinforcement ties was observed. Material strength and the amount of reinforcement ties used significantly contributing to the seismic behaviour of the structure.
