This paper investigates a new type of secondary beam through type concrete girder-steel secondary beam connection. In the core zone, the steel beam fully crosses through the concrete girder with an end plate welded at steel beam end. Static test was conducted on the 1/2 scale specimen to study the mechanical behavior and failure process of this type of joint during bending moments. Tests results indicate that the bending failure of steel secondary beam occurs, and the strength of steel secondary beam can be fully used. Test capacity value is slightly higher than theoretical calculation value. Steel beam was anchored well and no slippage failure occurred during load process. The specimen showed excellent deformation capability and ductility coefficient can reach 5.11.
