$($a$)$ The ACI Design Code limits the strain in tension steel $({}_t)$ to $0\mathrm{.}005$ while prescribing the maximum amount of reinforcement.

$($i$)$ True

$($ii$)$ False

$($b$)$ In the design of a singly reinforced concrete, the height was selected based on deflection requirement, and $A_s$ based on $(d-\frac{a}{2})=0\mathrm{.}9d_t.$ However, the section did not satisfy tension$-$controlled failure requirement. The following statement is true for redesigning this member.

$($i$)$ Increasing the area of tension steel is not an option

$($ii$)$ Increasing the height is not an option

$($iii$)$Increasing the width is not an option

$($iv$)$Increasing the concrete strength is not an option.

$($c$)$ The following statement is true for a one$-$way slab system.

$($i$)$ Both tension and shrinkage reinforcements are placed along the short span.

$($ii$)$ Tension reinforcement is placed along the long span and shrinkage reinforcement along the short span.

$($iii$)$Tension reinforcement is placed along the short span and shrinkage reinforcement along the long span.

$($iv$)$Both tension and shrinkage reinforcements are placed along the long span.

$($d$)$ The following statement is true for a T$-$beam when compared to a rectangular beam of the same height $(h)$ and web width $(b_w),$ except for the flange width $(b_f).$

$($i$)$ The depth of neutral axis $($c$)$ is higher $($numerical value$)$ for the T$-$beam.

$($ii$)$ The depth of neutral axis $($c$)$ is lower $($numerical value$)$ for the T$-$beam.

$($iii$)$The depth of neutral axis remains same for both the beams.

$($iv$)$ The information provided is not adequate.

$($e$)$ In arriving at the rectangular stress block from parabolic, the depth of the stress block is reduced by ${}_1,$ to achieve the following:

$($i$)$ To increase the factor of safety

$($ii$)$ To maintain equilibrium

$($iii$)$To keep centroid of the force same

$($iv$)$All the above
