Deep beams are characterized by small shear span-to-depth (a/d) ratios in which plane sections do not remain plane and the response of the members becomes governed by the details of their geometry. Their load-carrying mechanism can be idealized as a series of compression struts and tension ties, similar to a truss. In deep beams supporting wide loading elements, such as hammerhead piers or transfer girders supporting walls, it is common for the stiffness of the loading element to be higher than the supporting deep beam. This compatibility requirement leads to a more complex stress distribution underneath the wide loading or supporting element than in situations with narrow loading or supporting elements. Specifically, these conditions can result in high stress concentrations underneath the edges of the loading element and can cause the location of the resultant strut force to be moved further towards the edge of the loading element. This shift in the location of the stress resultant has significant effects on the angle of the diagonal compression strut and can significantly increase the member capacity relative to beams with the same a/d ratios but smaller loading elements. This thesis will present the results of six deep beam tests with varying a/d ratios and loading plate widths. The tests will be examined using light-emitting diode (LED) data, as well as digital image correlation (DIC) data. Additionally, the ability of the ACI and CSA strut-and-tie methods, the Two-Parameter Kinematic Theory (2PKT), and the nonlinear finite element program VecTor2 to predict the overall response of deep beams is examined.
