Abstract
Many adjacent structures have been built in recent years due to population growth and the unplanned urbanization. The mass and stiffness differences of the structures cause collions with each other. Since behavior of structures having different dynamic properties will be different, the pounding forces occur between structures during earthquake. In this study, collision behavior in adjacent structures was investigated. The nonlinear spring Hertz model was used for modelling of collision. Existing structures were modeled with Sap 2000 program, by considering horizontal rigidity, story level and gap parameters as variables. Slab-column and slab-slab collision situations were taken into account in the structures. Dynamic analyses of the structures were performed by using Kocaeli earthquake data according to different gaps. Displacements and pounding forces of the structures were obtained and the results were compared. It was determined whether gaps calculated according to the Turkish Building Earthquake Code 2018 (TBEC-2018) were sufficient in the structures.
