Study on Shear Performance of Web-Embedded Composite Shear Connector
Source abstract
Abstract
Based on the existing research on connectors, a web-embedded composite shear connector was proposed in this paper. Further, six types of push-out specimens were carried out on static push-out and low-cycle repeated load tests. The failure forms, load–slip curves, and load–strain curves of the tests are analysed. On the basis of the experiment, the finite element analysis is also carried out to enlarge the parameters of the specimens. The results showed that the shear stiffness of the web-embedded composite shear connector was larger than that of pure stud shear connector or perfobond rib shear connector, the slip limit was smaller, and ductility was good. A parameter analysis showed that penetrating steel rebars have the greatest impact on ultimate shear bearing capacity, reaching 43.82% of ultimate shear bearing capacity. Following repeated loading, the ultimate shear bearing capacity of the specimen decreased, the ultimate slip increased, and the ductility decreased. Based on the experimental results of this study, a new calculation equation for the ultimate shear bearing capacity of a web-embedded composite shear connector was proposed with a finite element model for verification.
