In this study, the design of the isolation system was carried out using the Effective Earthquake Load Method defined in Turkish Building Earthquake Code 2018 (TBEC-2018). Taking into account the TBEC-2018 criteria, a lead rubber isolator was designed for a 4-storey reinforced concrete structure and it was aimed to determine the effect of characteristic strength ratio (Q/W) and isolation period (T) variation on seismic isolator behavior for different soil classes. In addition, the effect of the distance from the fault line was examined, and for this purpose, two locations were selected in Sakarya, one close to the fault line (Arifiye), and the other far from the fault line (Karasu). Displacement, shear force and acceleration-displacement response spectra at the seismic isolation level were determined. Base shear ratio-displacement graphs were obtained in order to enable the designers to quickly determine the design parameters of the isolation system. In the research, it was concluded that the distance from the fault line, soil class, isolation period value and characteristic strength significantly affect the maximum isolation displacement and maximum isolation force values.
