The impact of strikes with the strong ground movement of neighboring buildings with insufficient space distance can significantly affect performance levels. This structural irregularity, called the pulling effect, can cause many damage to the structures of different dynamic characters and even gross migrations. In our country there is a potential of collision due to the construction of many structures of low and medium height, which make up a significant part of the housing stock, in a neighboring range or in a lack of space distance. It is very important that these structures are properly demonstrated by seismic performance. In this study, the aim was to determine the impacts of dragging on the seismic performance of existing structures of low and medium floors by dynamic analysis in the time-defining field. The study took into account two different regulations, the 1975 and the 1998 Earthquake Regulations, when building models were created. As a result of the inventory work, plastics are identified in the column and curve ends to reflect the nonlinear behavior in the 4 and 7 floor concrete buildings models created to reflect the average of about 500 buildings. Three-dimensional (3-B) modeled 4 and 7-storey building models were derived by connecting linear link (gap) elements to each other from floor levels. The reference that has not seen collision is left 400 mm between the two models, while the two models where the lack of gap is represented are left 0 and 20 mm. As a result of the dynamic analysis, the seismic performance of the building models has been seriously affected due to the drainage. For many drive records, the regulatory limits in the model’s shift requests have been exceeded and the impact of the collision and sudden demand changes have been shown to cause serious changes in the proportional rate of overlap. The study shows that it is not possible to properly assess the seismic performance of existing structures without taking into account the drawing effect.
