Ignore the compare to example question, please draw all profiles nicely.

Question $1$:

A reinforced concrete beam has the cross$-$sectional properties

shown to the right. Determine the points on the moment$-$curvature

response diagram corresponding to:

$($a$)$ Cracking moment $($use elastic uncracked analysis$)$

$($b$)$ Yield moment $($use cracked elastic analysis$)$

$($c$)$ Nominal moment capacity $($use equivalent rectangular stress

distribution$)$

Compare the response of this member to the response of the member

we studied in class. Comment on the differences you observe.

Draw $($for each one of these cases$)$ the strain profile, stress profile, as

well as the sectional resultant forces.
