| Abstract: | A new push out test method for perfobond rib connector was proposed and 7 different groups, totally 21, push out testing specimens were carried out. The load relative slip relationships of the specimens were tested and their failure modes were observed. The testing results show good reproducibility of load relative slip curve in each group, which proves the rationality of the proposed testing method. The failure property for the perfobond connector and influence factor for its shear bearing capacity are analyzed. |
