The ACI and CSA design codes offer no unified method for evaluating the deformability of fiber-reinforced polymer (FRP) reinforced-concrete (RC) structures, although numerous experimental results for such elements are available. This study discusses the methods for quantifying the deformability in FRP-RC structures. The methods were assessed based on the experimental results of four full-scale RC shear walls: three reinforced with FRP bars and one with steel bars

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

Effort has been given using non-linear 3D FEM program to predict the punching shear failure mechanism and its strength of steel-concrete open sandwich slabs with stud. In the analysis the stud is modeled by link element whose constitutive model is derived from the authors' experimental study. The results show very good agreement between the analytical and experimental values. Punching shear failure phenomena is carefully examined in the analysis observing predicted concrete cracking pattern and concrete crushing

the establishment of several construction applications of FRP reinforcement, there is a need for a system to resist lateral loads induced from wind and earthquake loads in these constructions. Reinforced concrete shear walls have shown effective performance in resisting lateral loads caused by wind and earthquake loads. Therefore, shear walls are frequently used in parking garages and multi-story buildings exposed to high lateral loading. This research involved testing a shear wall totally

This study represents a new step in using the finite-element method (FEM) as a powerful tool to simulate the seismic behavior of shear walls reinforced with glass-fiber- reinforced polymer (GFRP) reinforcement, which were tested and demonstrated the method's applicability as a lateral resisting system. The simulation analysis was performed on four large-scale mid-rise reinforced-concrete shear walls—one reinforced with steel bars and three totally reinforced with GFRP bars. Plane-sectional analysis and FE simulation

Abstract The external bonding of fibre-reinforced polymer (FRP) sheets to reinforced concrete (RC) structures has emerged as a popular method of strengthening. With this strengthening method, the stress transfer performance of the FRP-to-concrete interface is of crucial importance. Indeed, a number of failure modes associated with FRP strengthened RC members are directly caused by debonding of the FRP from the concrete. The motivation for this work is the fact that, although there is a large amount of experimental data

Beam type specimens where studs are used as shear connector are prepared to investigate constitutive relations. Parameters are stud height, compressive strength of concrete, stud spacing and steel plate thickness. The influences of these parameters are investigated in this study. The influence of the stud height is evaluated quantitatively and the influences of compressive strength of concrete, stud spacing and steel plate thickness are evaluated qualitatively

Well-designed shear walls can be used effectively as a primary lateral-load resisting system for 26 both wind and earthquake loading in multistory buildings. Glass-fiber-reinforced polymer 27 (GFRP) shows considerable deformability under monotonic and fatigue loading in reinforced 28 concrete structures. In this study, four large-scale mid-rise reinforced concrete shear walls—one 29 reinforced with steel bars and three totally reinforced with GFRP bars—were tested to failure 30 under quasi-static cyclic loading
