ABSTRACT

The present work reports the experimental research carried out to study a strengthening method for flat slabs under punching using transversal prestressed bars. Variations of this method have been studied by various authors namely: Ghali et al. (1974), Ramos et al. (2000), El-Sakawy et al. (2000) and Harajli et al. (2006). Eight experimental slabs were produced and tested. The experimental results are compared with a prediction based proposed model.
