Fibre Polymer Strengthening of In-Plane Restrained Slabs
PhD project Description
With ever increasing demands to strengthen existing reinforced concrete structures to facilitate higher loading due to change of use and to extend service lifetime, the use of fibre reinforced polymers (FRPs) in structural retrofitting offers an opportunity to achieve these aims. To date, most research in this area has focussed on the use of glass fibre reinforced polymer (GFRP) and carbon fibre reinforced polymer (CFRP), with relatively little on the use of basalt fibre reinforced polymer (BFRP) as a suitable strengthening material. In addition, most previous research has been carried out using simply supported elements, which have not considered the beneficial influence of in-plane lateral restraint, as experienced within a framed building structure. Furthermore, by installing FRPs using the near surface mounted (NSM) technique, disturbance to the existing structure can be minimised.
The aim of the project is to investigate the relative influences of compressive membrane action and the strength enhancing effects of retrofitting existing floor slabs with FRP bars using the NSM installation technique.
To date, the research has involved the development of concrete mix designs, materials testing of concrete, steel reinforcement and FRP bars along with microscopy measurements using optical and scanning electron microscopes.
Additionally, seventeen third scale in-plane restrained slab samples have been constructed, tested, analysed and modelled in both ABAQUS and LUSAS nonlinear finite element analysis packages.
