Q1. What are the different types of connections in steel structures.
Ans. 
Different types of connections in steel structures include welded connections, bolted connections, and riveted connections.
• Welded connections involve joining steel members by welding them together.

• Bolted connections use bolts and nuts to connect steel members.

• Riveted connections use rivets to connect steel members.

• Other types of connections include pinned connections and moment-resisting connections.

• Examples: Welded be...read more

Q1. Wind calculation as per IS code
Ans. 
The procedure for wind calculation as per IS code involves determining the design wind speed, selecting the appropriate terrain category, and calculating the wind pressure.
• Determine the design wind speed based on the location and height of the structure.

• Select the appropriate terrain category (rural, urban, etc.) as per IS code guidelines.

• Calculate the wind pressure using the formula provided in the IS code.

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

Q1. Thumb rules for sheet metal design
Ans. 
Thumb rules for sheet metal design include minimum bend radius, hole spacing, and material thickness considerations.
• Minimum bend radius should be at least equal to the material thickness to avoid cracking

• Hole spacing should be at least 2 times the material thickness to prevent distortion

• Material thickness should be chosen based on the application and required strength

• Avoid sharp corners to reduce stress concentrations

• U...read more
