A+ 2025/2026
Bending moments can occur in axially loaded RC columns due to which of the following factors? Check
all that apply.
Unbalanced floor loads
Misalignment of columns in upper stories
Misalignment of steel reinforcement
Use of lightweight concrete - correct answer ✔Unbalanced floor loads
Misalignment of columns in upper stories
Misalignment of steel reinforcement
Columns with dimensions less than 10 inches are rarely used in typical structures for which of the
following reasons? Check all that apply.
Difficult to bend transverse reinforcing ties
Columns this small will always be prone to buckling
Difficult to construct due to cover and spacing requirements - correct answer ✔Difficult to bend
transverse reinforcing ties
Difficult to construct due to cover and spacing requirements
In the LRFD design of RC columns, which design conditions must be satisfied? - correct answer ✔phi Pn
>= Pu AND phi Mn >= Mu
Match the column loading conditions with the corresponding depth, c, to the neutral axis.
Pure axial load (compression) c = infinity
Pure beam behavior Must solve for c
Onset of concrete tension c = h (section depth)
