The effects of changing story number and structural footprint area on building performance in reinforced-concrete buildings

Abstract

Structural footprint area and number of stories occupy an important place among the factors affecting the behavior of buildings under earthquake effects. In this study, footprint area and number of stories are considered as two different variables. A sample reinforced-concrete building with all values such as structural system elements, dimensions, materials, material models and loading status is selected same in all different structural models. The structural analyzes were made for a single direction since the structure was chosen symmetrically. In each building model, the axle clearance has been increased by one meter in both directions. As the second variable, four different story numbers were chosen as 5, 6, 7 and 8. Eigenvalue and static pushover analyzes were performed for the each structural model. Target displacement for damage estimation, period, stiffness and base shear force values were obtained for all models, respectively. As the building footprint area and number of story increase, period, displacement and target displacement increase, while stiffness decreases in this study.
