A portion of three$-$story school building second floorplan is shown in the figure below. The slab is $150mm$

thick with ceramic tiles $)$ on $13mm$ mortar bed floor finishes. The girders that carry the slab has a

dimension of $300mm$ by $450mm.$ The intermediate beam has a dimension of $250mm$ by $300mm.$ The $150$

mm$-$thick masonry wall has a total height of $3\mathrm{.}5$ m$.$ Use NSCP $2015$ values.
