A Study on Steel Pipe Coupler for Splicing Spiral Rebars

나선철근 이음을 위한 강관압착식 커플러에 관한 연구

The spiral provides the column with the ability to absorb considerable deformation prior to failure. Although this toughness is the principal gain that is achieved by the use of spiral reinforced columns, the its serviceability is limited by the fault of lap splices. The mechanical connection for the spiral bar placement is development in the study. The study contains for the experiment of the mechanical connection.
