Problem # $1$: $(50\%)$ Dead Load Determination

Part a$)$ Roof

Densit $=150e\frac{b}{1}\frac{c^3}{23\mathrm{.}6}B\frac{m}{m^3}$

A roof system consists of the following components

An $8-$inch thickness reinforced concrete $(RC)$ slab. $\frac{13816}{h^3}\frac{?}{21\mathrm{.}7h}\frac{N}{m^3}$

The top of the slab was finished with $1-$in terrazzo on stone$-$concrete fill. $32$ ps $\frac{?}{0\mathrm{.}14k}\frac{N}{m^2}$

The RC slab was cast on top of an $18-$gauge metal deck.

Below the metal deck there is a suspended metal lath and cementplas for the sprinklers and air

You must consider a mechanical duct allowance for the sprinklers $0\mathrm{.}19m\frac{N}{m^2}$ conditioning ducts that are placed on the ceiling.

if$)$ of floor

Determine the floor system dead load, in pounds per squar imensions are $25ftx20ft.$

Reference the ASCE $7/16$ standard and copying the code description of the the table, and the pou selected. component $($item$)$ you selected.
