Numerical models and analysis methods for beam-cable-membrane structures

摘要

In this paper the numerical method is presented for form-finding analysis and loading case analysis of beam-cable-membrane structures. The initial form of structures can be effectively found and the corresponding shape and stress distribution can be easily obtained by the method of this paper. Based on the solutions from form-finding analysis the responses of structures under external loads can be analyzed by nonlinear finite element method. Numerical examples show the efficiency of the method of this paper for large-scale structures.
