Problem $1-$ Determine the live load $($psf$)$ for the usage$/$occupancy types shown below per CBC $2019$:

Problem $2-$ The floor system of a gymnasium consists of a $130-$mm thick concrete slab resting on four

steel beams $($Cross section area of each beam, $A=9,100m{m}^2)$ as shown in the plan view below. The two

exterior beams A$-$E and D$-$H are supported by the columns at $A,E,D,$ and $H,$ respectively. The two

interior beams B$-$F and C$-$G$,$ are supported by girders A$-$D and E$-$H$,$ at the locations shown. Each girder

has a cross section area of $25,600m{m}^2.$ Determine the dead loads $($in KN$/$m or KN$)$ acting on beam B$-$F

and girder A$-$D$.$ The unit$-$weights of concrete and steel are $2,400k\frac{g}{m^3}$ and $7,850k\frac{g}{m^3},$ respectively.

Problem $3-$Rework Problem $2,$ except the distance between $E$ and $H$ is $3$ at $6m=18m.$
