ANALYSIS OF FINK ROOF TRUSS GENERAL DATA IN DETERMINING THE DESIGNING STRESSES OF A FINK ROOF TRUSS 1. Span, L= 35.0 meters 2. Pitch = one fourth 3. Bay Length 4.0 meters 4. Condition of supports: a. Right end support = roller b. Left end support = hinged 5. 6. 7. DEAD LOADS: a. b. C. d. e. f. 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 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 U₁ J U₂ U3 L₂ M U4 U3 U₂ U₁ S.
