Problem $2$:

A two$-$span continuous beam is subjected to service superimposed dead load $w_{SDL}=10$

$k\frac{N}{m}$ and service live load $w_{LL}=15k\frac{N}{m}$ along its length. Determine the steel

reinforcement for the beam within the maximum positive and maximum negative

moment regions using $f_c^{\text{'}}=35$MPa $($Normal weight$)$ and $f_y=420$MPa. Use the ACI

coefficient method to determine the critical moment diagram and consider the beam's

weight. Assume the clear concrete cover on $($No$.10)$ stirrup is $40$ mm $.$
