$($Analysis type problem$)-$ Assume that the compression stress block is within the flange.

i$)$ For the T beam shown, using first principles calculate the nominal moment capacity $($Mn$)$

ii$)$ Calculate strain in tensile steel ${\displaystyle \underset{t}{\overset{?}{}}}$ iii$)$ Is the res a$)0\mathrm{.}9$

b$)$ greater than $0\mathrm{.}9$ or

c$)$ less than $0\mathrm{.}9$

Why?

$F_y={60}^{\text{k}\text{s}\text{i}}$

$F_c=4^{\text{k}\text{s}\text{i}}$
