- Abstract
The test results on shear walls with glass fiber-reinforced polymer (GFRP) reinforcement have proven the applicability of such structural members in resisting lateral loads and strongly suggested the necessity of proposing a design procedure for them. The elastic and inelastic deformations were identified and suggestions for appropriate definitions provided. The force modification factor Rd was estimated based on the idealized curve of the tested shear walls. The virtual plastic hinge lp for GFRP-reinforced walls was described and its length estimated based on experimental observations and calculations. The ultimate limit state was addressed by providing a strength capacity that limits ductility demand to the structure's safe deformation capacity. Deformation capacity was derived by estimating virtual yield and maximum allowable deformations. Using the suggested values of Rd and lp produced consistent results for the deformation-demand equation. Subsequently, the proposed design guidelines were verified based on the experimental results of the GFRP-reinforced shear walls.
