HIGH-STRENGTH CONCRETE SHORT BEAMS SUBJECTED TO CYCLIC SHEAR
Six high-strength concrete model short beams were tested under cyclic shear in a double curvature condition. Experimental parameters included reinforcement configurations, clear span length-to-section depth ratios ranging from 3.0 to 4.0 (shear-span-to-depth ratios of 1.5-2.0), and flexural reinforcement ratios ranging from 2.3% to 4.5%. The stirrup design was based on the seismic design provisions of the American Concrete Institute (ACI) 318-95 Code. All the model beams developed flexural yielding prior to sliding shear failure corresponding to a displacement ductility factor of 3.5-6.2. The flexural strength calculated based on the ACI 318-95 Code approach was developed or exceeded. Compared with beams with conventional reinforcement configuration, the model beams with vertically distributed flexural reinforcement developed significantly improved hysteretic performance and ductility.
