1. Select the most probable use of a square hollow structural section.

2. The _____ frame has primarily pin-type connections and relies on some type of members to provide lateral stability.

3. What is the difference between a pin-type connection and a rigid connection?

Solution

1. Square hollow structural section have uniform geometry and thus uniform strength characteristics. Hence, it is most preferable for column.

Hence, correct option is C.

2.braced frame has primarily pin type connection and lateral stability is provided by tension and compression bracing.

Hence, correct option is C.

3.

Rigid connections transfer bending forces and gravity loads.

Hence, correct option is D.
