PERFORMANCE BASED DESIGN IN SEISMIC DESIGN

The design of a geotechnical structure under seismic loading is frequently carried out by means of the pseudostatic approach, checking the system against all possible geotechnical and structural ultimate limit states.

The analyses developed according to Eurocode 8 and Italian Code lead to an over-conservative geotechnical design.

Keeping in mind the importance of strength hierarchy and ductility concepts when designing for seismic conditions, the research focuses on the possibility that methods of current practice can be used efficiently for seismic design if Performance Based Design principles are taken into account.
