Eleven provinces along the East Anatolian fault line have been severly affected from the Pazarcık M7.7 and Elbistan M7.6 earthquakes which occured in Kahramanmaraş, Türkiye on February 6, 2023. Many buildings in these provinces were totally collapsed. However, it is observed that several buildings located in the vicinity of the collapsed buildings which received adequate engineering services either sustained controlled damage or did not receive any damage at all in accordance with their design target. It is clearly observed that bearing soil conditions have a significant effect on the level of damage to buildings during these earthquakes. Most of the buildings that were destroyed or severely damaged during these earthquakes were built on very weak soil such as alluvium. However, it is another fact that the centers of the cities were located on soft soil near rivers or plains having agricultural value. In this case, it is clear that the first attempt to be made is to reconstruct the cities where they used to be. It is also of great importance that the city center of Antakya, which is known to have an important value in terms of the Middle East history and the history of religions is included in the UNESCO World Heritage List. Hence, the city has to be reconstructed in the place where it is used to be. Considering the importance of the methods to be developed using high technology to increase the earthquake performance for the construction of the city center, a pilot study is conducted by choosing an existing zone with 9 apartment blocks at the city center. For this purpose, a block in Antakya General Şükrü Kanatlı Quarter with 9 buildings consisting of 5 and 8 floors is chosen as the pilot project region. A method has been developed to reconstruct these 9 structures in the region with seismic isolation. The foundation, insulator and plinth floors of the pilot region are designed as a single monolithic base and separate residential blocks placed on it. Basement floor consists of parking lots and shops. This study offers an economical solution that is safe against earthquakes, solves the parking problem of the blocks, and enables using infrastructure services of the central region of the city by preserving the current location and silhouette of the region, seismically protected with advanced technology.
