“The influence of cable sliding on the structural response of a large pneumatic envelope”, Proceedings of the International Association for Shell and Spatial Structures (IASS), 2015, Future Visions, 17-20 August 2015, Amsterdam, The Netherlands
ABSTRACT: This paper presents the formulations of a sliding-cable super-element and a membrane element capable of representing wrinkling, whose stiffness matrices are obtained through finite-differences, thus requiring the sole definition of force vectors. These formulations are then applied to the analysis of a large pneumatic membrane reinforced by cables, and the effects of adherent or sliding conditions on the system’s structural response are investigated.
