Η παρούσα εργασία ασχολείται με τον ανασχεδιασμό υπάρχοντος πολυώροφου κτιρίου με σεισμική μόνωση και συγκρίνει τη συμπεριφορά του σεισμικά μονωμένου με το αντίστοιχο συμβατικά εδραζόμενο κτίριο. (EL)

The main purpose of the present study is the earthquake resistant design of a multi-storey building with seismic isolation and the comparison of the seismic response of a conventionally supported (fixed) and a seismic isolated building. In the first chapter, a short description of the sense and the basic philosophy of seismic isolation,which is in complete contrast with the conventional antiseismic design, is made. The basic benefits of seismic isolation are mentioned,too. In the second chapter, the way of seismic isolation’s action is analysed , as well as the structural details, as they are defined in Eurocode 8 for seismic isolated buildings. In the third chapter, a specific reference to the application of seismic isolation in existing buildings is made. Specifically the conditions of application are analyzed, the possible mounting positions of the isolators is specified and the installation process is analyzed. The fourth chapter gives examples of seismic isolation and a brief historical overview. The Parthenon is also shown as an early form of seismic isolation. The fifth chapter is a quick reference to the various types of seismic isolators and their modes of action. The sixth chapter is a reference to three methods of analysis are as follows: 1) the method of equivalent SDOF system, 2) the spectral analysis and 3) the non-linear analysis histories, as well as to the necessary checks of the isolators as defined in Eurocode 8. In the seventh chapter a reference to the model of the superstructure and the isolators and to the loads that strain the structure, is made. Thereafter, in the eighth chapter, the analysis procedures of isolated buildings according to codes are presented. Particularly, equivalent linear, modal linear and time-history analyses are described. Finally, safety verifications for ultimate limit state have been reported. In the ninth chapter some comparative diagrams of sizes between the conventional-founded building, whose analysis has been made with q=1 and the seismic isolated with the new ξ are presented. In the tenth chapter the procedure followed for the institution simulation with SAP2000 is explained step by step. (EN)
