Abstract

"The use of reinforced concrete (RC) allows for unique designs of structural elements and connections because of the ability to vary the geometry and reinforcement detailing with ease. However, this freedom in the design process can lead to specialized conditions that have not been extensively studied by means of experimental testing. This is especially true for components or regions of components that are subjected to high shear loads, which are susceptible to undesirable and brittle failures. While many studies have been conducted to investigate the shear behavior of RC structural members and components to determine the critical design parameters, these tests are typically modeled after basic structural geometry and loading conditions. In modern design, geometry constraints and higher demands have pushed the envelope on RC structural members and components leading to wider beam members that are supported on narrower columns as well as connections requiring direct shear transfer across an interface to meet design demands. This study employed 3D nonlinear FEA to develop analytical models to investigate the internal forces within wide RC beam members and monolithic interface connections when subjected to shear loading. The analytical models were utilized to conduct parametric studies and develop insights into the effects of these unique conditions on the shear performance. Finally, a proposed prediction model was developed to estimate the shear transfer strength along a monolithic and non-monolithic interface connection using the results of the parametric study and data from literature" -- Abstract, p. iii
