$($a$)(2$ points$)$ What are the reinforcement limits $($i$.$e$.,$ limits of As$)$ of flexural design of rectangular or nonrectangular shaped beam sections. Let b or bw $=10,$ h $=20,$ and d $=17.$

$($b$)(2$ points$)$ What are the reinforcement limits $($i$.$e$.,$ limits of As$)$ of flexural design of one$-$way slabs. A
