Abstract: To establish the expression of shear capacity of PBL (Perfobond Leiste) connectors, monotonic loading push-out tests of eight PBL connectors were carried out. The influences of different bearing types, concrete strength, the number of hole(s) in the steel plate and the diameter of transverse rebar passing through the hole(s) on the shear capacity of PBL shear connectors in static loading were investigated emphatically. According to the deformation compatibility condition, the contribution of end concrete, concrete dowel and transverse rebar passing through the hole(s) to shear capacity of the shear connector with single hole were analyzed. The shear capacity of connectors with multiple holes were obtained by the superposition of the shear capacity of connectors with single hole on the basis of stress redistribution. Experimental results showed that the calculation model of the shear capacity had clear physical meaning and desired computational accuracy. The calculation model can be used to calculate the shear capacity of single row PBL shear connectors.
