초록

This paper focuses on the static behavior of prestressed and non-prestressed connections for the steel-concrete hybrid girder. Based on the experimental study, it is found that the girder with non-prestressed connection failed by local concrete failure at the connection area, and the studs are taken out from the concrete. In case of the girder with prestressed joint, the failure of the girder is initiated by the crack at the varying section area. The test results show that the girder with prestressed connection has higher load carrying capacity compare to the girder with non-prestressed connection by 12%. Therefore, the application of prestressing at the concrete-steel connection recommended for the more secure connection.
