Highlights Shear transfer behavior of RC strengthened using bolted steel plates were tested. Mechanism for the increase of shear transfer capacity was revealed. Expression to predict ultimate shear transfer capacities was proposed.
Abstract Reinforced concrete (RC) with steel bars set across a shear plane was strengthened using bolted steel plates to transfer shear force. Nineteen Z-series specimens were tested to investigate shear transfer behavior with bar ratios varying from 0.46 to 1.2% and steel plate ratios ranging from 3.57 to 10.42%. Nine D- and B-series specimens were tested to assist to understand shear transfer mechanism by means of a shear component model. In this model, the shear transfer resistance was provided by different sources, i.e., friction, aggregate interlock, adhesion, shear dilation, dowel action, and steel plate resistance. Results found that the ultimate shear transfer capacities increased by 15–57% with a ductile failure mode. The increase of the shear transfer resistance was primarily due to two factors: 1) the increase of the shear components of friction, aggregate interlock, and shear dilation caused by the additional transverse clamping force provided by the steel plates and 2) steel plate resistance. Expressions were developed to predict the ultimate resistance of shear transfer of strengthened RC with approximate accuracy.
