Question

Which of the following is true regarding arrangement of leaving a gap between the ends for column splices?

(a) load is transferred through splices

(b) splices are designed only to resist accidental tension

(c) load is transferred through contact area

(d) splices are designed only to resist bending moment

I have been asked this question in final exam.

This intriguing question originated from Beam and Column Splices in portion Bolted Connections of Design of Steel Structures

Answer 1

Correct answer is (a) load is transferred through splices

Best explanation: When the columns carry predominantly axial forces, leaving a gap between the ends may be used. In this case, the whole load is transmitted through means of splice plates. HSFG bolts may be used in the connections and changes in size of column may be accommodated using packing plates.
