Battening is preferable when
- AColumn carries axial loads only
- BSpace between the two main components is not very large
- CBoth (A) and (B)Correct
- DNone of the above
Solution
Concept
When battening is preferred over lacing
Step-by-step solution
1. Battens are used when the column carries axial loads only and the distance between the main components is not large. 2. For eccentric loads or larger spacing, lacing is preferred.
Explanation
Battened columns are suitable for axially loaded members when the components are close. Where the loading is eccentric or the spacing is large, lacing provides better shear resistance.
Shortcut
Battens: axial load + close spacing. Lacing: eccentric load or wide spacing.
Common mistake
Choosing a single condition.
Correct answer: C) Both (A) and (B)
