碩士 === 國立臺灣海洋大學 === 河海工程學系 === 97 === Cable trusses are commonly used in structural engineering to function as the roof systems of large-span structures. Because cable trusses is a problem of geometric nonlinearity, much different from conventional structures such as trusses and plane frames, the effect of geometric nonlinearity plays an important role in determining the response to applied load. Consequently, the paper is to make use of Green-Strain and Newton-Raphson method. To proceed nonlinear structures analysis and to calculate buckling’s critical condition, and according to Perturbation Techniques to confer the strength and the displacement relation in after Post-Buckling. The paper through analysis buckling load and Post-Buckling’s stable behavior of cable trusses with parallel and double-concave and double-convex chords. And further, to discuss Pre-Strength parameter and geometric parameter regarding influence of cable trusses. The effect of the researching paper could apply in analysis and design such as cable trusses and plane frames.
