Abstract

There are many fault lines within the borders of our country, especially the North Anatolian Fault line. For this reason, earthquake resistant structural design is a very important issue in order to prevent possible economic losses after earthquakes, especially the life safety of people living in our country. The main goal in earthquake insulation, which is a new approach in earthquake design of buildings, is to reduce the possible effects on the structure by placing flexible elements in the horizontal direction and rigid in the vertical direction, by greatly reducing the earthquake loads and accelerations acting on the superstructure. In this study, the earthquake behavior of the buildings, which were designed by the Housing Development Administration of the Republic of Turkey and designed as a base isolation support, and the structures designed according to the principles determined in the Turkey Building Earthquake Code 2018 by using base isolation, were determined according to the non-linear time history analysis method. The behavior changes of the structure designed using earthquake base isolation compared to the conventional structure were examined, and the period values, floor accelerations and base shear forces of the two structures were compared. As a result of the results obtained, the positive effects of the period increase and the decrease in floor accelerations in the earthquake insulated structure were revealed.
