In the present paper, a formulation for analytical study of cable roof system is presented wherein the flexibility of supports bounding the roof is accounted for. The analytical work is based on Finite Element method and accounts for non-linearity for of cable assembly using Newton Raphsons method. The supporting structure is however, treated as being linear. Using this approach, a generalised computer program has been developed for analysis of a bicycle wheel type cable roof. A parametric study by changing stiffness of beam and load intensities has been carried out on a experimental model of 3-meter diameter and the effect of flexibility of supporting structure on maximum deflection, prestress in cable roof and bending moment in the ring beam has been studied in particular. Finally the developed algorithm has been used to verify the maximum deflection of Auditorium Roof, Utica, N.Y., U.S.A..
