TASK $4(15)$

The beam in Fig $4$ uses N$32$ Concrete. Exposure A$2,$ M$*=375kNm$

$($a$)(5)$ Determine the effective depth $\text{'}$d$\text{'}$ assuming a steel ratio of

$0\mathrm{.}8p_{\text{m}\text{a}\text{x}}$

$($b$)(10)$ Calculate the area of tensile reinforcement required, the overall

depth $\text{'}D\text{'}$ of the beam, and complete the cross section detail in Fig $4$

showing all details as worked out above.
