Abstract

This study is to investigate experimentally the shear capacity of high-strength reinforced concrete beams subjected to monotonic loading. Nine reinforced concrete beams using high strength concrete $(f'c=380kg/\textrm{cm}^2)$ are tested to determine their diagonal cracking and ultimate shear capacity. The main variables are shear span-depth ratio a/d=1.5, 2.5, 3.5, and shear reinforcement ratio. All specimens are 170mm wide and have a total depth of 300mm. The test results indicate that ACI 318-95(b) Code for shear capacity gave closest agrement with the exsprimental results. The beams with a shear spear-depth ratio 1.5 and 2.5. ACI 318-95 Code underestimates shear strength carried by vertical shear reinforcements.
