In case of Beam-to-Column connection, there are three types of connections namely Simple Connection, Semi-rigid Connection and Rigid Connections. Following are the various types of beam-to-column connections as shown in the figures below. Identify the 'Rigid Connection'
- ADouble web angle
- BTop and seat angle with double web angle
- CTop and seat angle without double web angle
- DEnd plate without column stiffnersCorrect
Solution
Concept
Types of beam-column connection
Step-by-step solution
1. Double web angle is a simple (flexible) connection. 2. Top and seat angle (with or without web angles) is semi-rigid. 3. An end plate connection without column stiffeners is shown as the rigid one.
Explanation
Moment transfer through the flange plate/end plate gives rigidity.
Why the other options are wrong
Angle connections transfer little moment.
Shortcut
Angles = simple/semi-rigid; end plate = rigid.
Correct answer: D) End plate without column stiffners
