Abstract

Abstract

In order to study the mechanical properties of large-opening saddle-shaped orthogonal cable network structures， a 1∶10 scale model was designed based on the Xi’an International Football Center. Bearing capacity tests were carried out on the large-opening saddle-shaped orthogonal cable network structure. The testing process， which included full-span， upper half-span， and right half-span loading of the cable net， was simulated using the general finite element software ANSYS. The results showed that under the three loading modes， the axial force in the upper load-bearing cables gradually decreased from the edges toward the center of the cable network， while the axial force in the upper stable cables decreased from the central axis toward the edges along the long span. Both the cable internal forces and the vertical deformation of the cable network exhibited an approximately linear trend with increasing load. Additionally， the cable network underwent only minor in-plane deformation. Under full-span loading， the opening expanded slightly outward in the short-axis direction and contracted slightly inward in the long-axis direction.
