The subject of this research is the study of the strength and behavior of multi-story buildings constructed by the tunnel-framework technique subjected to earthquake excitations. For this purpose, a section composed of the connection regions of the structural walls which are the vertical members and the floors which are the lateral members of the buildings constructed by the tunnel-framework technology is modeled. The modeled structural system has been tested under reverse-cyclic loading within a lateral load testing frame assembled from steel profiles at Selcuk University, Engineering-Architecture Faculty, Civil Engineering Department Structures Laboratory. The reversed-cyclic loading are applied on the models at the 4th, 3rd and 2nd floor levels by varying the parameters belonging to the amount of reinforcement and keeping the thickness of shear wall and slab constant. In order to determine the effect of the spacing of vertical reinforcement in reinforced concrete shear walls, experiments have been carried out on three different models namely Type-A; Type-B and Type-C. The diagrams of moment-curvature, load-deformation and load-displacement of the bottom of shear wall are plotted with respect to the reinforcement patterns used in the specimens. These values are compared with each other and with the results obtained from the theoretical study.Moreover, for the shear wall sections, the moment capacities of the embedded reinforcing bars atthe time of failure are discussed experimentally and theoretically. By inspecting the cracks of themodel shear walls occurred during the application of lateral force, some conclusions have been madeabout the failure modes.
