Dynamic Behaviour of a Seismic Isolated Structure in Greece

Abstract eng:
Onassis House of Letters and Arts is a cultural center with hallmark architecture. In order to satisfy the architectural requirements as well as the high performance seismic specifications that were set, a seismic isolation system of FPS type bearings was employed. This study focuses on the methodology followed for the seismic design which, performed in three consecutive steps, includes simple calculations using an equivalent SDOF model, dynamic response spectrum analyses and non-linear time-history analyses using selected earthquake records on a 3-D finite element model. Results indicate good agreement between different analyses and shed light to the behavior of a complex, seismic isolated structure under seismic loads.
