What is importance factor I for a commercial building?
Being an office building, the importance factor, I, is 1.0 (Table 6 of IS: 1893). Building is required to be provided with moment resisting frames detailed as per IS: 13920-1993. Hence, the response reduction factor, R, is 5.
What is a seismic factor?
The seismic importance factor (Ie) is used in the Seismic Response Coefficient (CS) equations with the intent to raise the yield level for important structures (e.g., hospitals, fire stations, emergency operation centers, hazardous facilities, etc.).
What is importance factor for seismic design?

Why do I believe motivation is the most important factor?
