What is the main difference between a column and a strut?
A
Struts carry tensile loads B
Columns are always horizontal C
Struts can be inclined or horizontal D
Columns are made only of concrete
Analysis & Theory
Struts can be vertical, inclined, or horizontal; columns are usually vertical.
Which column type is reinforced with a spiral reinforcement?
A
Tied column B
Composite column C
Spiral column D
Axial column
Analysis & Theory
Spiral columns use helical reinforcement for confinement.
Which failure mode is associated with long slender columns?
A
Shearing B
Buckling C
Torsion D
Crushing
Analysis & Theory
Long columns fail primarily by buckling under compression.
What is the slenderness ratio of a column used for?
A
To find length of beam B
To classify long or short column C
To calculate shear strength D
To measure deflection
Analysis & Theory
Slenderness ratio helps determine whether a column is short or long.
Which of the following is NOT a column type?
A
Short column B
Spiral column C
Cantilever column D
Composite column
Analysis & Theory
Cantilever is a beam term; not a standard column classification.
