Seismic isolation method is an innovative mature performance enhancement strategy to mitigate the earthquake risk on structures. As a result of the targeted response modification, feasible engineering solutions can be achieved during the service life of structures. For both bridges and buildings simplified analysis procedure of seismic isolation systems are set forth in guide specifications and design provisions. Equivalent lateral force (ELF) method in buildings can be considered as the simplest method of analysis with high importance. This procedure can be directly used in the analysis and design of seismically isolated structures or it can be used in the establishment of lower-bound limits to nonlinear time history analysis. This paper focuses on the overview of design procedures of isolated buildings and comparison of the analysis results of ELF procedure based on selectively well-known codes and guidelines used in pioneering countries. The buildings were equipped with two commonly used isolation systems named as lead rubber bearing and curved surface friction sliders. A comparison of the 2016 Edition of the Turkish Seismic Design Code with the US(ASCE/SEI 7–10), the European (Italian version of the Eurocode (EC-8) application, NTC-08) and the Japanese (Building Standard Law-2013) codes is conducted on the implementation of the ELF Method for parametric study of structures located at sites of similar probabilistic earthquake hazard in respective countries. Recommendations and concerns associated with the current-state of practice and ongoing development new reference section of TSDC are highlighted by comparing code compliance approaches and practical applications.
