Geometrically Nonlinear Analysis on a Double Controlled Form Finding Method Considering Construction Process of Suspen-Domes

Abstract:

Based on the time-varying suspen-domes model, a configuration-cable force dual control form-finding algorithm was proposed, taking the construction process and construction technology into consideration, according to the looped cable tensioning construction technique, especially in the practical project. The form-finding algorithm was complemented by inverse iteration method for controlling the structure configuration and the initial stress increment method for controlling the cable force. Furthermore, the influence of geometric nonlinearity, construction process, and other construction technology could be taken into consideration.
