Presence of openings in reinforced concrete beams enables the installation of these services, minimizes the required floor height, and decreases the construction cost. However, the presence of these openings in reinforced concrete beams affects their structural behavior. Thus, this thesis investigates the behavior of simply supported beams with openings in shear zone subject to two symmetrical-concentrated loads UR - http://172.23.153.220/th.pdf ER -
