A continuous rectangular beam

with a $300550mm$ cross section

has a clear span of $7,600$ mm$.$ In

addition to its own weight, the

beam must carry a dead load of

$20k\frac{N}{m}$ and a live load of

$30k\frac{N}{m}.$ The beam is designed

with $3-30$M bars in the midspan

region and $5-30M$ bars in the

support regions, as shown.

$f_c^{\text{'}}=35$MPa and $f_y=400$MPa

Determine if the beam design

satisfies code requirements for:

$($i$)$ allowable reinforcement ratio

$($ii$)$ reinforcement detailing

$($i$.$e$.,$ cover, spacing$)$

$($iii$)$ flexural capacity

Assume that the continuous beam

comprises more than $2$ spans, is

designed for interior exposure

conditions, and that also contains

$10$M stirrups $($which are not

shown in the figure$).$
