Strengthening of Reinforced Concrete One-Way Slabs for Flexure Using Composite Materials: Evaluation of Different Composite Materials

Abstract

This study was conducted to evaluate the flexural performance of simply supported one-way reinforced concrete (RC) slabs strengthened using three different types of composite materials. The composites materials that used in this study were polyparaphenylene benzobisoxazole (PBO) with a cementitious-based curing agent (FRCM), carbon fiber grid with polymer curing agent (CFRP-grid), and steel reinforced polymer system (SRP). The first aim of this study was to investigate the effectiveness of these composite materials in upgrading the flexure capacity of one-way RC slab systems in terms of the load-deflection, failure mode, and displacement ductility performance. The second aim of this study was to investigate the effect of the environmental conditioning on the stiffness and flexural performance of the composites.
