내하성능 개선을 위한 강관형 전단연결재의 실험적 연구

This study proposes skewed pipe shear connector for improvement of connection performance between horizontally adjacent precast box girders. Shear and pull-out tests are performed to evaluate load carrying capacity of skewed pipe shear connectors. Push-out test is performed on specimens considering diameter and embedment length as variables to evaluate shear resistance. 4-point bending test is performed on specimens considering embedment length and angle of steel pipe as variables to evaluate pull-out resistance. Based on the Result of these tests, load carrying capacity of loop joint and skewed pipe shear connectors are compared.
