Design a baseplate $($pin connection $)$ for the column $A-B$

if $B-C$ section is $W41075$ and $A-B$ is $W41075$

P$3=0,W1=100K\frac{N}{m},P1=5KN,P2=5KN,$ add the own weight of the column, neglect

beam weight

$L=7\mathrm{.}5m,H1=3m,H2=5m,P1$ at $\frac{L}{3},P2$ at $2\frac{L}{3}$

notes : choose proper materials, all loads are unfactored Dead loads
