Abstract
A study was conducted to secure structural performance as well as improve workability by improving the reinforcement details of special shear wall and coupling beams. Based on the specimen in which the existing diagonal bundle reinforcement and shear reinforcement were placed, the specimens replaced with thick diagonal reinforcing bars and the specimens replaced with horizontal reinforcing bars were selected as variables. As a result of the experiment, the specimen, which replaced the existing diagonal reinforcement with a thick-diameter reinforcement, showed a similar behavior to that of the basic specimen, and it was evaluated that it can be applied as an alternative to the details.
