Research on Sliding Cable with a Nonlinear Analysis Method for a Cable-Membrane Structure
Cable sliding in membrane pockets or on membrane surfaces has not yet been considered in analysis of cable-membrane structure software. In this study, a new sliding cable element has been created, using the non-linear finite method and a model of line-elastic and non-linear sliding stiffness. First, this paper outlines existing computational methods for creating sliding cables and questions the accuracy of these current numerical models. Second, it determines the sliding stiffness of sliding cables by examining the relationship between the original length and the end tension of space two-node linear cable elements. Third, the solution arithmetic for cables sliding in membrane pockets or on membrane surfaces is proposed with consideration of correctional linear sliding stiffness. Finally, the method developed herein is validated by one example.
