Experimental study on the cracking resistance of dovetail-shaped RPC wet joint in composite deck system

摘要

The crack resistance of a composite RPC deck system withdovetail-shaped wet joint was investigated by experimentalstudy. The dovetail-shaped RPC wet joint presented satisfactorycrack resistance. The initial crack stress and nominal tensile atthe interface were about half that of the fully site-cast RPC layer.AcknowledgementThis research was supported by the Natural ScienceFoundation of China (Grant No. 51708466).
