Question $1$:

A Classroom floor in an elementary school, subjected to the following loads:

The classroom is without fixed seats;

Dead $($D$)=3\mathrm{.}1$kPa including self$-$weight;

Live $(L)={2\mathrm{.}4}_{k}Pa-$ use table to find out the load;

Snow $(S)=3\mathrm{.}2$kPa; and

Wind $(W)=1\mathrm{.}55$kPa $($pressure$).$

Compute the critical factored load using the load combinations from table $3.$ With the floor layout as shown below, calculate the magnitude of the distributed load on the external beam $($AB$)$ and internal beam $($CH$).$
