| 摘要： | In this paper, novel geometrically nonlinear analytical solutions (NASs) and linear analytical solutions (LASs) for the postelastic response analysis of biconvex and biconcave prestressed suspension cable trusses subjected to a uniformly distributed load are presented. The derived analytical method provides a straightforward determination of the intensity of vertical uniformly distributed loads applied over the entire span of a structure, as well as the accompanying forces and vertical deflections corresponding to the postelastic behavior of cable trusses. In this solution, the direct use of experimental data, such as the actual stress-strain properties of high-strength steel cables, is implemented. Resultant forms of the deflection and cable equations are modified because of the effects of geometrically nonlinear truss behavior in the postelastic range that need to be incorporated. The application of the described approaches and derived equations is illustrated by numerical examples. Resultant responses (forces and deflections) of the biconcave cable truss in the postelastic range obtained by the present geometrically nonlinear and linear analytical solution are compared with those obtained by the nonlinear FEM. |
