Research on influence factors and formulae for the bearing capacity of angle shear connectors

Relying on a practical application in pre-stressed concrete box-girder with corrugated steel web, four angle shear connector specimens are made and experimented in push-out test. The results show that: in the ultimate load level, failure model appears after large slip occurring between connector and concrete which shows a good ductility of angle shear connector. The main influence factors for the bearing capacity of connector is thickness of angle web, U-shaped steel provides certain shear resistance ability to same extent. Finally, through the contrast analysis between measured values and theoretical values, a new bearing capacity formula is proposed. Compared with the recommended formulae, the calculated results from proposed formula is most close to the text results, thus new formula can be used for security design and calculation.
