Since the height and span values of the deep beams are close to each other, there are situations where openings are left in the deep beam body for the installation of electricity, water, sewage, communication, heating and ventilation installations of the buildings. Due to the placement and geometric shape of these openings left in the beam body, much more complex changes in structural behavior are observed, and nonlinear approaches come to the fore in stress and strain calculations. In this study, the modification of the structural behavior of a deep beam in the presence of regular geometric openings is investigated using the finite element method. The study was carried out in four phases and in the first phase, the appropriate size and material properties of the deep beam elements with regular openings were determined. In the second stage, the deep beam elements whose dimensions, material properties and reinforcement details were determined were modeled with ABAQUS software using finite element modeling technique. In the third phase, the load arrangement to be applied to the deep beam was determined, and in the last phase, the displacement-controlled static analysis of the deep beam was performed depending on the determined loading arrangement. The aim of the study is to determine the impact of regular geometric spans in the deep beam web on the collapse behavior, maximum load carrying capacity, ductility and stiffness of the beam}, number={2}, publisher={İdris Karagöz}
