Examining of building bearing system behavior for different slab types

Although the earthquake is a natural disaster that cannot be avoided all over the world, the fact that the earthquake is a disaster causing loss of life and property for people can be eliminated by designing and constructing earthquake resistant structures. Due to its monolithic and rigid structure, the most damaged buildings during the earthquakes and the migrants are observed are reinforced concrete structures. In the earthquake resistant design of a reinforced concrete structure, the horizontal and vertical displacements and periods of the structure under the effect of the actual earthquake effects or the predicted earthquake forces are examined and a safe and economic structure design is carried out so as not to exceed the limits stipulated by the regulations. In the literature, although it is accepted that the beams columns and walls constituting the frame system play an effective role in determining the horizontal and vertical displacements and periods of a reinforced concrete structure, in general, all the vertical and horizontal loads carrying and transporting plaque systems in the structural behavior of it has been investigated that it can play an active role. Also in Turkey Building Earthquake Code (2018), in determining the ductility of the structural system, the type and shape of the slab behavior under impact load it is important. Therefore, the effect of different slab types on the behavior of the structure under the effect of earthquake loads was investigated in this thesis. In this study, it is aimed to compare the earthquake performance of beamed slab, flat slab, one way ribbed (hollow block) slab and waffle slab construction systems. For this purpose, 3, 4 and 5 story buildings were modeled according to TS500 and TBDY (2018) principles according to 4 different slab types. Earthquake calculations of the modeled buildings were made according to the equivalent earthquake load method. It is assumed that the local soil class is taken from the geotechnical report ZD. As a result of the analysis, natural vibration periods, base shear forces, maximum horizontal displacements and relative floor shifts of the buildings were compared. The results of the analysis of the building models were examined and it was found that beamed slab systems gave the most appropriate values. In this context, in order to see the effect of floor height and number of floor changes on carrier system behavior, building models with 4-6-8 storeys and floor heights of 3-3.5-4 meters have been created. Earthquake calculations of the buildings were made with Sap2000 finite element software.
