¿ä¾à2 Because boundary confinement details proposed in the current design standards are significantly inferior in workability and productionquality, it is necessary to develop boundary confinement details of RC structural walls that are capable of ensuring seismic performance andworkability. With the recent development of the wire rod manufacturing technology, various pre-fabricated continuous hoop details can bemanufactured. In this study, an analysis was conducted on the moment-curvature relationship of RC structural walls to which thepre-fabricated continuous hoop details were applied. According to the nonlinear cross-section analysis, the RC structure wall to which thedetails of the pre-fabricated continuous hoop details are applied can ensure seismic performance as the area of the pre-fabricated continuoushoop increases. Based on these research results, when applying the pre-fabricated continuous hoop in detail, it is necessary to secure the area ofthe pre-fabricated continuous hoop as much as the area of the existing boundary confinement.
