Seismic Performance Finder (“SPF”)

This is one of the VIS family of tools. It allows for the calculation of the critical elastic spectrum corresponding to an existing RC structure, allowing for the evaluation of the Seismic Performance of the building according to Eurocode 8-3 and Italian NTC 2018.

Based on a reference Response Spectrum provided by the user and on the reinforcing assigned to the members in the VIS model, the application calculates the critical scale factors for the seismic action both in terms of strength and drift limitation.

From the results the program derives a Rating Index depicting the seismic proficiency of the structure.

The whole process is highly iterative and involves SPF interacting with SAP/ETABS and VIS, while managing many Response Spectrum analysis runs.
