Abstract:

It is expected that the designed structures will behave at a certain level of performance under design loads. The effects of structural system properties on the behavior of the structure are quite high. For this reason, the arrangement of the structural system of the structures, the dimensioning and placement of the carrier elements greatly affect the behavior of the structure under the effect of earthquakes. With today's technology, it is not possible to predict the time of earthquakes before a certain period of time. However, it is possible to build earthquake-resistant structures. It is important for multi-storey reinforced concrete buildings to have sufficient rigidity and strength and to limit displacements under the influence of earthquakes. At this stage, the use of shear walls in building design is used as an alternative. The geometry of the shear walls in the carrier system and their position in the plan affect the behavior under earthquake loads. In this study, the effect of the geometry of reinforced concrete shears and their different placement in the plan on the structural behavior was investigated. For this purpose, the results obtained from the modal and earthquake analysis of seven different buildings, whose structural system is reinforced concrete frame and shear wall frame, were compared. In the comparison, the mass, period, base shear force, torsion coefficient, relative interstory drift and overturning moment values of the buildings were taken into account. It is possible to see the effect of different geometry and placement of the shear walls in all the parameters examined.
