Influence of the Reinforcement with Fibre-Reinforced Polymer Fabric on the Seismic Loading Behaviour of a Reinforced Concrete Building

Abstract

The current paper analyzes the influence of strengthening by implementation of glass fiber reinforced polymers (GFRP) to evaluate the seismic load performance of a building with reinforced concrete frames using a non-linear static method. By use of the computational program ETABS V18.1, two types of building models are created and analyzed; one model without any strengthening and the other reinforced with GFRP. Differences between the values of the displacement from the top of the building, basal shear and yield displacement, performance point and level as well as basal shear displacement values at the top corresponding to the formation of plastic hinges in beams, columns and the appearance of the first collapsed element are reported and established for both models. It is concluded that the strengthening by the implementation of GFRP favorably modified the performance of the building, since the capacity to withstand earthquakes increased, the formation of the collapsed mechanism is delayed and the level of performance is improved in relation to the building model without strengthening
