Lateral ties in reinforced concrete columns are provided to resist ____
Show Hint
Functions of lateral ties:
\[
\boxed{
\begin{aligned}
&\text{Prevent buckling of longitudinal bars}\\
&\text{Provide confinement to concrete}\\
&\text{Hold reinforcement in position}
\end{aligned}
}
\]

- Bending moment
- Shear
- Buckling of longitudinal steel bars
- Both bending moment and shear
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: picture a slender reinforced concrete column under axial load.
The main longitudinal bars are thin and long compared to their diameter, so under heavy compressive load they behave like individual slender struts and want to bow outward sideways.
Step 2: see what stops this bowing.
Lateral ties are wrapped around the longitudinal bars at regular intervals, holding them in position and shortening their unsupported length, which directly resists this sideways buckling tendency.
Step 3: separate this from bending and shear resistance.
Bending moment and shear in a column are primarily resisted by the concrete section and the main longitudinal steel working together, not by the ties, so those two options do not describe the tie's real purpose.
\[ \boxed{\text{Buckling of longitudinal steel bars (option C)}} \]

- Consider the beam section shown in the figure, with \( y \) indicating the depth of neutral axis (NA). The section is only subjected to an increasing bending moment. It is given that \( y = 18.75 \, {mm} \), when the section has not yielded at the top and bottom fibres. Further, \( y \) decreases to 5 mm, when the entire section has yielded. The shape factor of the section is ........ (rounded off to 2 decimal places).
\begin{center} \includegraphics[width=8cm]{53.png} \end{center} - Consider a reinforced concrete beam section of 300 mm width and 700 mm depth. The beam is reinforced with the tension steel of 2000 mm² area at an effective cover of 50 mm. Concrete in the tension zone is assumed to be cracked. Assume the modular ratio of 12 and Young's modulus of 200 GPa for steel. When the extreme fibre in the compression zone undergoes the strain of 0.0004 due to the applied bending moment, the stress in the steel (in MPa) is ..... (rounded off to the nearest integer).
