Please solve the problem using a pin and a paper. It is easier for me to understand.

$1.$ Assume the frame shown below is only subjected to uniform dead and live loads, and that their values are the same for the first and second floors.

a$)$ Given the reinforced concrete beam cross sections shown below the frame, determine the maximum value of qu that may be applied to satisfy ACI $318-19.$ Assume that the two beam sections are typical for sections corresponding to either positive or

negative moment, respectively.

b Find the uniform service load that can be applied if $30\%$ is dead load and $70\%$ is live load.
