Assessment of shear effects of RC beams and columns on seismic performance of RC structures

Shear failure plays a significant role in the seismic behavior of reinforced concrete (RC) structures. Generally, nonlinear analysis of the beams and columns in concrete structures is based on the flexural behavior of the members, and shear effects are generally ignored. Although in such an analysis...

Generally, nonlinear analysis of the beams and columns in concrete structures is based on the flexural behavior of the members, and shear effects are generally ignored. Although in such an analysis, only the flexural behavior of members is considered, experimental results reveal the likelihood of the failure of RC members before reaching the ultimate flexural capacity. In this paper, a numerical model including rotational springs was developed to simulate the effects of the shear capacity of beams and columns based on material failure mechanisms. In order to evaluate the accuracy of the proposed model for beams and columns, the results gained by the nonlinear analysis were compared with the experimental results, which revealed a good agreement of the results predicted by the proposed model with those of experiments. Furthermore, the proposed model was assessed at the structural level in terms of performance, and to do so, an RC frame was investigated in two different modes: a) analysis using the proposed model considering shear effects and b) analysis based on the proposed model ignoring shear effects in the members.
