Abstract

The Deep Embedment (DE) or Embedded Through Section (ETS) technique is a new retrofit method to increase the shear capacity of reinforced concrete (RC) structures using fibre-reinforced polymer (FRP) or steel bars. Following the development of this technique, the structural behaviour of RC continuous beams strengthened with the DE method needs to be investigated rigorously by considering key influencing parameters. In this research project, ten tests were performed on 3840 mm long RC continuous T-beams designed to fail in shear. The research presented here is focused on the extension of the Deep Embedment technique to consider T sections, GFRP and steel bars besides CFRP bars, angles of drilling other than vertical, and the effects of continuity on shear strengthening. Therefore, the main objective of this study is to expand our current knowledge on the behaviour of continuous beams strengthened in shear with DE bars by varying the parameters previously mentioned. The basis for an analytical model required to validate results collected and to predict behaviour of such strengthened beams is presented.
