Abstract
This study investigated the performance of recycled waste fishing net sheets (WSs) as a sustainable strengthening material for reinforced concrete (RC) slabs. The primary challenge addressed is the debonding failure caused by the low bond strength at the WS-to-concrete interface. To analyze this, two full-scale RC slabs-one with and one without strengthening-were cast and tested under a four-point bending setup. Finite element (FE) models incorporating existing bond-slip laws were developed using the ABAQUS software to simulate the strengthened slab's behavior. A sensitivity analysis was performed to assess the impact of bond-slip parameters on the failure mechanism. Experimental results indicated that the WS-strengthened slab enhanced the RC slab capacities by 15% in yield load and 13% in initial stiffness. Furthermore, the maximum shear stress of 0.5τ<sub>max</sub> or interfacial fracture energy of 0.2G<sub>f</sub>, compared to values proposed by Monti et al., enabled the simulation of the global response observed in the experiment.
