Question

Lateral ties in reinforced concrete columns are provided to resist ____

• A. Bending moment
• B. Shear
• C. Buckling of longitudinal steel bars
• D. Both bending moment and shear

Hint:

Functions of lateral ties: \[ \boxed{ \begin{aligned} &\text{Prevent buckling of longitudinal bars}\\ &\text{Provide confinement to concrete}\\ &\text{Hold reinforcement in position} \end{aligned} } \]

Answer 1

The Correct Option is C

Step 1: Recall the function of lateral ties. Lateral ties in reinforced concrete columns provide lateral support to the longitudinal reinforcement.

Step 2: Identify their primary purpose. They prevent the longitudinal bars from buckling under compressive loads and also help confine the concrete core. Hence, \[ \boxed{\text{Buckling of longitudinal steel bars}} \] is the correct answer. Therefore, \[ \boxed{(C)} \] is the correct answer.
