Performance of GFRP bar anchored PBO-FRCM composite on one-way RC slabs under flexure
2019
The use of FRCM (Fabric Reinforced Cementitious Matrix) composites for reinforced concrete elements structural strengthening is gaining increased popularity. This causes the need to better understand the work of the material and to propose an effective way of using it. The mechanical behaviour of FRCM composites related to their ductility and tendency to debond or delaminate causes that its typical use, known from the older FRP (Fibre Reinforced Polymers) technology, is inefficient, that was the reason for the anchoring concept. This paper presents the results of the research based on three slab type elements, two of which were strengthened with one layer of PBO-FRCM composite with GFRP rebar anchorage of the composite mesh ends. The most important mechanical properties of the elements were measured and analysed.
