speed of 39 m/sec

Assume i] Normal permeability, Cpi=+0.2

ii] External wind co-eff k$_{1}=1$, k$_{2}$=0.91, k$_{3}$=1 used bolted taint connection

Geometry of Truss:

Rise R=tan30$^{\circ}\times$4.5 =2.6m

enter image description here Panel length =$\frac{25.2}{3}$=1.73

C.c spacing of truss =4m(given)

c/c spacing of purline=1.73

load calculation per panel point

Dl per panel point ... on plan …
