Experimental Studies on Nonlinear Behaviours of Reinforced Concrete Panels Subjected to Cyclic In-plane Shear

In this study the leakage of pressurized water through direct tension cracks in reinforced concrete (RC) panels is investigated experimentally. The results of the experiment can contribute to the field from different aspects since not many experimental studies of this kind have been reported in the literature. In this experimental program, three RC panels are subjected to direct tension force in order to form a major crack. The leakage test is then performed on the cracked specimens and the leakage of water through the crack is measured for different crack widths. The collected data consists of reinforcement strains, crack widths and the leakage rate through the cracks. Related theoretical models are compared against the experiment results. These results indicate that the leakage of water through a crack depend on the pressure of the water, cube of the crack width and crack width gradient.

Out Of Plane

Cross ties have been widely used in Steel plate Concrete (SC) structures. It is considered as one of the most effective methods in ensuring the integrity of the SC module when subjected to both flexure and out-of-plane shear. Although there are no specific guidelines for the design of cross ties as shear reinforcement in the current practice, the requirements for reinforced concrete structures specified in ACI 349 has been generally adopted in design. The experimental studies completed at the University of Houston show that a minimum amount of cross ties is required for the SC structures to preserve shear ductility. This amount was found to be greater than the ACI 349 recommendations. In addition, the strength of SC beams could not be predicted by the ACI 349 code. This paper evaluates the applicability of the present shear design methods of reinforced concrete beams to steel plate concrete beams and proposes a set of shear design equations.
