Abstract

With the effect of the increasing population in Turkey, a rapid construction need has emerged, and accordingly, an increase has been seen in housing construction. Since the 1980s, our country has initiated the construction of reinforced concrete buildings, resulting in a significant building stock. For this reason, the majority of the current building stock consists of structures manufactured according to the principles of the 1975 Disaster Regulation. The February 6 Kahramanmaraş earthquake shows that the earthquake performances of these buildings are more fragile than those constructed under the 1998 regulation. The main reasons for this fragility are deficiencies in quality of workmanship, poor manufacturing in concrete quality, and the use of unribbed reinforcement. Within the scope of this study, a building constructed according to the principles of the 1975 Turkish Seismic Code was considered, and a comparison was made between the earthquake performance of the building with different densification and manufacturing details in the columns. As a result, it was determined that in the event of full implementation of the principles of the 1975 regulation, a life-safety damage level was achieved for the determined building according to the principles of the 2018 Earthquake Regulation.
