摘要：

A numerically efficient procedure is presented for generating the stiffness of a parabolic, three-node finite element for the static, nonlinear analysis of three-dimensional cable-supported structures. Numerial computations are minimized by explicitly evaluating the large deformation stiffness matrix with respect to global coordinates while avoiding incompatibilities with existing, displacement-based elements. Representative improvements are illustrated by using three typical geometrically nonlinear, cable supported structures. Also, an efficient method is presented to evaluate the self weight profile of a pretensioned inclined cable.
