A Stiff Test Facility for Obtaining Controlled Shear Failure of Reinforced Concrete Beams
An energy absorbing stiff test facility has been developed for obtaining stable and controlled shear failure of reinforced concrete beams. Using two hydraulic jack and a cross steel beam to act as the stiffener and energy absorbing elements, test facility allows the monitoring of the complete curve of load versus mid-span deflection (including the post-peak region) of shear critical beams. To prove the feasibility of this test facility, the stiff test facility was measured when test facility were loaded up and down. Then, the shear failure experiments of 4 full size reinforced concrete beams were processed. The results indicate that the post-peak branch of the load versus mid-span deflection of the shear-critical reinforced concrete beams without web reinforcement was steeper than that of beams with web reinforcement and hence the stiff test facility was more stable for beams with web reinforcement.
