Earthquakes in the past, damage distributions, observations and teachings It has shown that all engineering structures in Kocaeli Province are under earthquake hazard. In this study, the contribution of the infill walls to the earthquake performance of the reinforced concrete building was investigated in order to ensure that the structures constructed with today 's knowledge and workmanship application experience remain at a limited level of damage against a possible large earthquake. In this study, 10-storey reinforced concrete building located at 40.77 latitude and 29.98 longitude coordinates in Izmit District of Kocaeli Province was selected as the working structure and numerical analyzes were conducted and earthquake response simulations were tested for a series of scenarios earthquake. Reinforced concrete building, which took place in Kocaeli 11 using massive earthquake station records, Turkey Earthquake Building Regulations 2018 have suggested that non-linear time history analysis done, contribute to performance against earthquake reinforced concrete building where it is available and there are unavailable infill walls were followed. As a result of the placement of the infill walls as symmetrical and partition elements on all floors of the reinforced concrete building, it was observed that the displacements and internal forces caused by the earthquake in the building carrier elements decreased. In addition, it was concluded that the building, which is normally observed to be damaged, has reached a limited level of damage as a result of the placement of infill walls as part of the partition walls. Finally, it was observed that the use of infill walls in reinforced concrete buildings increased the ability of building carrier elements to perform plastic deformation without collapse and consequently the damping rates in the building increased. In order to predict the performance of reinforced concrete buildings against earthquakes together with all existing elements, it is concluded that wall elements should be considered as bearing elements and should be included in the design. The results obtained within the framework of the study are inevitable in terms of reflecting the reality of the criteria and safe redistribution conditions by clarifying the definitions and functions of partition and bearing walls of building regulations.
