Seismic base isolation of a typical hospital structure with a friction pendulum isolator

Abstract

One of the biggest threats for structures built from past to nowadays in Turkey is earthquake. The concept of seismic isolation has been developed in order to keep the structures safe from the effects of the earthquake. Based on the idea of reducing earthquake loads acting on the structures, seismic isolation design is the most effective design technology to transfer earthquake loads to the structures. In this study, a three-dimensionalmodel of a typical hospital structure designed using a friction pendulum isolation system (FPS) with a curved surface is performed and its modal and earthquake analyses are carried out according to Turkey Building Earthquake Code (TBEC-2018). The earthquake performance of the structure is determined and compared with a conventional fix-base buildin
