Question : 24 of 65

Marks: +1, -0

Two rectangular under-reinforced concrete beam sections

{X}

and

{Y}

are similar in all aspects except that the longitudinal compression reinforcement in section

Y

10 \%

more. Which one of the following is the correct statement?

Solution:

Due to presence of more compression steel in section

Y

, NA of section of

Y

is above than as of

X

. It means

Y

is more under-reinforced than

X

so ductility of

Y

is more. Since compression steel of

Y

is more so flexure resistance of

X

is less than as of

Y
