Shear resistance mechanism of Perfobond strip (PBL) joint with cast-in-place UFC connection for UFC-PC hybrid girders has been studied. Push out test of eight specimens was conducted. Experimental parameters were thickness and hole diameter of PBL and prestressing level on the connection. The experimental results showed that PBL with cast-in-place UFC connection is sufficient to transfer shear forces between segments. Shear resistance mechanisms were investigated. The shear capacity increased as the fiction resistance by the prestressing stress on the connection.
