Given the following floor framing plan for the second floor of a library $($assume that the floor is dedicated for use as a series of stack rooms$)$:

a$.$ Using the ASCE $7$ Design Loads $($handout provided in class$)$ and a concrete unit weight of $145$ pcf$,$ what are the uniform distributed live and dead load loads $(w_L$ and $W_D)$ on BEAM $3?$

b$.$ What is the maximum factored distributed load on this beam $(w_u)$ based on load ASCE $7$ load combinations $1$ and $2?$ Hint: $U=1\mathrm{.}4D$ and $U=1\mathrm{.}2D+1\mathrm{.}6L$

c$.$ What is the maximum factored moment for this beam $(M_u)$ assuming that the beam is pinned at the ends $($simply supported$)?$

d$.$ Considering the case where the beams are simply supported $($part c$),$ what is the factored axial load $(P{u}_u)$ in column $A3?$
