Civil Engineering QUESTION #6616
Question 1
What is the primary reason for using a 'moment connection' instead of a 'shear connection' in a steel frame?
  • To reduce the cost of fabrication
  • To allow for easier thermal expansion
  • To provide lateral stability and resistance to wind/seismic loads✔️
  • To ensure the beam behaves as a simply supported member
Correct Answer Explanation
Moment connections (Rigid connections) transfer both shear and bending moments, allowing the frame to act as a rigid system that resists lateral forces through frame action (portal effect).
