Abstract: Selecting composite connection is a crucial factor for researching mechanical performance of GluBamconcrete composite beam． An initial stage of research on the feasibility of a type of notched connection for GluBamconcrete composite beam was described． Total 15 groups of bond and anchorage pull-out tests and 3 groups of shearslip tests were conducted respectively． The main mechanical properties such as anchoring capacity，load-slip curves and anti-slip stiffness were measured． The test results showed that liquid adhesive could penetrate GluBam easier and reach higher anchoring strength compared to paste adhesive． There was an optimum diameter for glued-in rebar according to the standardized anchorage strength，which almost did not fluctuate with anchorage depth． Setting inclination on the bearing surface of notched connector could not improve mechanical properties of this type of composite beams． But nailed to sides of GluBam beam prevented cracking of GluBam beam effectively and increased shear capacity significantly． Compared with GluLam-concrete composite beam with the similar notched connector，this type of new connector presents good mechanical performance while improved ductility． However only qualitative conclusions can be drawn at this stage，which needs to be investigated further．
