The Pratt roof trusses are uniformly spaced every 15 ft. The deck, roofing material, and purlins have an average weight of 5.6 psf. The building is located in New York where the anticipated snow load is 20 psf and the anticipated ice load is 8 psf. These loadings occur over the horizontal projected area of the roof. Determine the vertical deflection (in units of inches) of joint C due to the dead load, snow, and ice loads. Neglect the weight of the truss members and assume A is pinned and E is a roller. Each member is made of steel (E = 29,000 ksi) with a cross-sectional area of 1 in². -8 ft- -8 ft 8 ft -8 ft 6 ft 6 ft E The Pratt roof trusses are uniformly spaced every 15 ft.
