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

Strengthening two-way slabs by using fiber-reinforced polymer (FRP) is experimentally and analytically evaluated. Results show that the punching capacity of two-way slabs can increase to up to 40% greater than that of a reference specimen. A three-dimensional FEM program called 3D CAMUI, which was developed at Hokkaido University, was used to simulate the experimental slabs. Very good agreement is obtained in load-carrying capacity and modes of failure. An analytical model based on the numerical simulation
