Özet:

In this study, the behavioral changes on the building as a result of the use of shear walls in reinforced concrete buildings and the placement of these shear walls differently in the plan were examined. For this purpose, an existing building determined within the borders of Sakarya province has been handled, and the static and architectural project and ground survey reports of the building have been reached. In addition to the current situation of the reinforced concrete building, finite element models were produced using the IdeCad package program for 6 situations where the placement of the shear walls in the plan is different. In some of the models, the basement floor was completely surrounded by shear walls, and in some, frame systems were preferred without using shear wall elements in the carrier system. In the study, 6 structural models produced, including the existing reinforced concrete building, were analyzed using the mode combination method, which is one of the modal analysis methods, and it was aimed to determine the most suitable structure against the earthquake risk in the region. As a result of the analysis, the changes in structural parameters such as vibration period, base shear force, horizontal displacement, torsion coefficient, relative story drift and building cost were evaluated for each case, and the most suitable design for building type structures to be built in regions where earthquake risk is high was determined. As a result of the study, it was determined that the earthquake risk in both directions decreased most significantly in the model whose basement floor was completely sheared, but the cost of the building increased in parallel. On the other hand, it has been determined that the use of additional shear wall systems is a necessity in order to minimize the earthquake risk in the model whose carrier system consists only of frames.
