Given

h=6m[height upto eaves]

width w=9m

Ratio $\frac{h}{w}=\frac{6}{9}$ =0.67

AS per table $\frac{1}{1}\leq\frac{h}{w}\leq\frac{3}{2}$

enter image description here

i] wind perpendicular to ridge [wind word]

WL $_{1}$ =(-0.2-0.2) $\times$ 755.72= -302.29... Pa

WL $_{2}$ =(-0.2+0.2) $\times$ 755.72=0

ii) Wind perpednicular to ridge [Lee wared]

WL $_{3}$ =(-0.5-0.2) $\times 755.72$ = -529.0 Pa

WL $_{4}=(-0.5+0.2]\times 755.72$ = - 226.72 Pa

iii) Wind parallel to ridge[wind ward]

WL $_{5}=(-0.8-0.2)\times 755.72$ = - 7555.72 …
