摘要：The subject of this work is to present the structural analysis of a structure idealized by the architect Maurício Lippi G. Dias. This structure is to cover a bicycle races stadium to be built in Bosque da Barra in Rio de Janeiro. The structure has elliptical projection with 88m in smallest axis and 150m in largest axis. The tensile structure is supported by cables connected to piles located around the elliptical projection. The cables are connected to reinforced concrete foundations outside the elliptical projection. Inside the surface and the cables are connected to a steel ring with 38m diameter located in one ellipse focus. This work presents a finite elements model to design flexible structures by means of a specific computer program prepared by the author. The computer program allows to make physical or geometrically no-linear analysis. Incremental and iterative analyses are made to prepare the limit load curve. Results of the analyses including ring tension, support reactions in the piles, cables tension efforts and the more damaged areas in the surface located in the largest dimensions are presented.
