Abstract
Finite element techniques were applied to the analysis of a general curved frame stiffened with tension members. Curved stiffened frames are found in a variety of structures such as space structures and cable roof structures. A tennis racket was used as a specific example problem. The model discussed here has the flexibility to deal with any frame shape and stringing pattern. The strings of the structure are modeled using nonlinear cable theory. The frame is modeled with linear isoparametric elements. Group iteration is used to analyze the two substructures, resulting in displacements, forces, and stresses for the entire structure.
