Shear Creep Failures of Reinforced Concrete Slender Beams without Shear Reinforcement
This study aims at investigating the effects of sustained loads on the shear strengths of reinforced concrete (RC) slender beams. Slow loading rates (that were 100 and 1000 times slower than the normal loading rate) were selected to reveal creep effects. The slower loading rate indicated that increased creep occurred during the loading test. However, the shear strength was almost constant during the occurrence of significant diagonal cracking and it increased slightly at failure. It showed that a reduction factor for the shear strengths of the slender RC beams under sustained loads was not required in the design.
