![ANALYSIS OF FINK ROOF TRUSS
GENERAL DATA IN DETERMINING THE DESIGNING STRESSES OF A FINK ROOF TRUSS
1. Span, L= 35.0 meters
Pitch = one-fourth
Bay Length = 4.0 meters
Condition of supports:
2.
3.
4.
5.
6.
7.
a. Right end support = roller
b.
Left end support = hinged
DEAD LOADS:
a. Use corrugated asbestos whose thickness is 10 mm for roof covering weighing 220 Pa of roof
surface.
Assume weight of purlins to be 220 Pa
Weight of truss, use formula W = 35.90 (1+L/3.048)
It is assumed that two-thirds of the weight of the truss is carried on top chord an the remaining
one third on the bottom chord.
Assume weight of bracing = 90 Pa
Assume weight of ceiling = 370 Pa
Assume weight of ceiling joist = 130 Pa
b.
C.
d.
e.
f.
Assume wind velocity, V = 230 kPh and use P = 0.722V^2, where V is in m/sec
Assume LIVE LOADS to be 1130 Pa
