Q3. Staad model for fixed pole
Ans. 
A STAAD model for a fixed pole is a structural analysis and design model used to determine the stability and strength of a pole that is fixed in place.
• In a STAAD model for a fixed pole, the pole is typically modeled as a vertical member with fixed supports at the base.

• The model considers factors such as wind loads, dead loads, and any other relevant loads that may act on the pole.

• The analysis helps in determining the s...read more
