In prefabricated steel structures, which type of connection provides the highest resistance to seismic forces?
- ABolted shear connection
- BWelded moment connectionCorrect
- CSimple pin connection
- DFriction-grip bolted connection
Solution
Concept
Moment connections
Step-by-step solution
1. Welded moment connections give rigid, ductile joints.
Explanation
They provide the highest resistance to seismic forces.
Why the other options are wrong
Pinned and simple bolted connections transfer no moment.
Shortcut
Seismic = rigid moment connection.
Correct answer: B) Welded moment connection
