Time-history analysis of aggregate interlock in reinforced concrete beams without stirrups
Highlights Shear-transfer actions vary depending on a RC beam's different load and crack pattern states. Continuous measurements of crack kinematics for RC beams without stirrups are performed throughout all tests. Aggregate interlock stresses at critical crack are studied throughout all tests using non-linear Walraven model. Aggregate interlock contribution is insignificant until 90 %–98 % of the shear strength. Results bridge the gap between shear strength models with apparent contradictory initial hypotheses.
Abstract Different shear-transfer actions on concrete beams have been well-studied in many research works to understand the mechanical behavior of RC beams failing in shear. In this research, a detailed investigation is conducted to evaluate six simple supported RC beams without stirrups by the detailed tracking of crack kinematics with photogrammetry techniques. Research focuses on a refined measurement of crack kinematics throughout the experimental test for different longitudinal reinforcement ratios. The result highlights marked redistribution of shear-transfer actions very close to failure, where aggregate interlock contribution changes from irrelevant to primary. The principal remarks aim to gain a better understanding of rational approaches for shear design through critical shear crack behavior to bridge the gap between shear strength design models with apparent contradictory initial hypotheses.
