Bend-strength of novel filament wound shear reinforcement

The test results indicate that W-FRP shear links exhibit improved bend strength as compared to conventional stirrups with circular sections (up to +53%), as a larger width-thickness ratio of the reinforcement provided more strength for a given cross sectional area. A good correlation between the test results and predictions of the W-FRP bend strength was observed when the specimens were modelled as a collection of transformed individual circular sections.
