Abstract |
In this study, a shear experiment was conducted to evaluate the structural performance of RC members according to the shape of web opening reinforcement. For a total of 4 RC members specimens, the main variables were with or without web openings, with or without web opening reinforcement, and shape of web opening reinforcement, respectively. In this study, a spiral web opening reinforcement with a mixture of square and octagonal shapes was proposed and compared with the existing band type. As a result of the experiment, the specimen with the proposed web opening reinforcement showed that the shear capacity and the energy dissipation capacity increased compared to other specimens. It was confirmed that the web opening reinforcement proposed in this study had a positive effect on the shear performance and crack control of RC members with web openings.
