Given: the following floor framing system

Required: Determine the maximum moment and maximum shear in the beam by:

Considering the concentrated loads produced by the joist reaction on the beam for joist

spacing $s=\frac{l}{3},\frac{l}{4},\frac{l}{5},\frac{l}{6}$

$s=\frac{l}{3}$

Considering a uniform load $w(l\frac{b}{f}t)$ on the beam equal to the tributary width

$(\frac{l_1}{2}+\frac{l_1}{2}=l_1)$ times the uniform floor load $p(psf)$ i$.$e$.w=px{l}_1$

Compare the moments and shears in a table and comment on the results.
