Study on Shear Performance of Group Stud Connectors Based on Accelerated Corrosion Test
In order to study the degradation law of shear performance of studs under corrosion,the constant current accelerated corrosion test and push-out test were carried out on the composite speci-mens of group stud connectors.The results show that the corrosion of studs will not affect its failure mode,but will reduce the shear bearing capacity and ultimate slip value of the connectors.According to the shear bearing capacity of each specimen,the corrosion reduction function is fitted.It is found that the relationship between the shear bearing capacity of studs and the corrosion rate is exponentially reduced.
