This paper presents the results of an experimental and computational investigation tailored to examine the response of glass\r\nfiber-reinforced-plastic-(GFRP-) reinforced glue-laminated curved beams and arches. The main objective was to ascertain the\r\nviability of GFRP as an effective reinforcement for enhancing the load carrying capacity and stiffness of such curved structures.\r\nThe study included optimization of the length and thickness of the GFRP reinforcement. In doing so, first a parametric finite\r\nelement study was conducted to evaluate the influence of unidirectional GFRP reinforcement applied onto the arch using eleven\r\npossible configurations and different thicknesses. Subsequently, an experimental investigation was conducted to verify the results\r\nestablished by the finite element method as well as the integrity of actual GFRP-reinforced glue-laminated curved structures. The\r\nresults indicate that GFRP can be considered as an effective and economically viable solution for strengthening and stiffening\r\nglulam arches, without adding any appreciable weight to the structure.
