Résumé
In order to study means of improving the behaviour of thick slabs without shear reinforcement a series of large-scale beams representing thick slabs was constructed and tested. Companion specimens were strengthened using drilled-in reinforcing bars to study the effectiveness of this repair technique. The behaviour of these beams, before and after strengthening, is compared. An additional experimental program using pull-out specimens enabled a study of the bond characteristics of drilled-in reinforcement having different embedment lengths. An analytical model to predict the bond-stress versus slip relationship enabled the development of a method for predicting the influence of the added shear reinforcement in improving the shear strength. These predictions are compared with the experimental results and provide a practical means of assessing the influence of post-installed shear reinforcement.
