PROBLEM #$1$:

Given:

An interior beam supports the floor $($single floor$)$ of a classroom in a school building. The beam span $L={26}^{\text{'}}-0^{\text{'}\text{'}}.$ and the tributary width $s=18\text{'}-0^{\text{'}}.$ Dead load $=20$ PSF$.$

Find:

A$.$ Basic floor live load $L_0$ in PSF

B$.$ Reduced floor live load L in PSF per ASCE $7-16$ Equation $4\mathrm{.}7-1$

C$.$ Reduced floor live load L in PSF per $2018$ IBC, Section $1607\mathrm{.}11\mathrm{.}2$

D$.$ Uniformly distributed total load to the beam in PLF based on value obtained in parts $B$ and $C.$ Compare obtained values.
