D$/3$P$1$:

A typical$-$cross section of a reinforced concrete

T$-$beam is shown in the figure below. The beam is

reinforced with $7-35M$ bars. The material properties

are summarized below.

Find the factored moment resistance for the beam

section.

Given:

$f_c^{\text{'}}=30$MPa

$f_y=400$MPa

${}_c=0\mathrm{.}65$

${}_s=0\mathrm{.}85$
