Analysis of Shear Transfer in Reinforced Concrete with Application to Containment Wall Specimens
In this report the shear transfer mechanism across continuous cracks penetrating through the thickness of a reinforced concrete element are investigated. The parameters influencing shear stiffness of the cracked sections are identified. Based on these parameters a mathematical model is developed for the prediction of the shear stiffness. This model is used to evaluate the shear rigidity of orthogonally reinforced concrete panels exhibiting parallel or orthogonal through cracks. The model is applicable to biaxially tensioned wall specimens subjected to monotonically increasing tangential shear stress. For two test specimens, the shear rigidity as predicted by the proposed model is implemented in a finite element computer program. Three dimensional finite element analysis is performed for these specimens to study the behavior of a containment wall portion under biaxial tension and tangential shear loading. The influence of the crack patterns and their stiffness on shear deformation and reinforcement stresses in the specimen is evaluated. The proposed model and analysis procedure predict shear rigidities and structural responses consistent with the observed behavior of the test specimens.
