76 X1 Category 1: Buildings Project History In 2006, the Stavros Niarchos Foundation (SNF) announced its intention to fund the creation of the Stavros Niarchos Foundation Cultural Centre (SNFCC), a project that includes the construction and complete outfitting of new premises for the National Library of Greece (NLG) and the Greek National Opera (GNO), as well as the development of the 170,000 m² educational and cultural Stavros Niarchos Park. The project has a budget of €566 million.

Part of the scope was the verification of the main two seismically isolated buildings: the Opera House and the National Library buildings. The original analysis has been performed using Etabs, while for the verification Scia Engineer and ECtools were chosen. Opera House It is an R/C structure with seismic isolation in the basement. The building is 100 x 100 m in plan and has the height of 32 m for the R/C part. On top of the building rests a ferrocement canopy which is supported by steel columns, spring dampers and post-tensioned X bracing on the R/C structure below. Library It is an R/C structure with seismic isolation in the basement. The building is 95 x 95 m in plan and has the height of 30 m for the R/C part The design verification for both buildings consisted of at least the following tasks: • Selection of inverted pendulum isolators • Checking the capacity of R/C walls and cores • Checking the capacity of large beams (200 cm x 200 cm) and waffle slabs with wide spans • Checking deflections • Checking temperature effects • Checking creep effects All those tasks were executed using Scia Engineer and ECtools.
