The Analysis Of Initial Form-Finding And Load Effects Of Floating Membrane Structure

Floating Membrane Structure is a new type of Membrane Structure which produces by introducing aerostat concept into the field of Membrane Structure. Based on the principle of Cellular Automata, the paper puts forward a new analytical method of Membrane Structure, and also has a form finding and load effect analysis of Floating Membrane Structure by Self-developed dynamic simulation system in order to identify feasibility of Floating Membrane Structure applied to practical construction.Membrane Structure design methods based on the principle of Cellular Automata is a new calculation and analysis method which integrates the simulation ideology of Cellular Automata with dynamic relaxation method of traditional analytical methods of Membrane Structure and introduces dynamic effect of load into dynamic relaxation method. Based on the new design methods, the paper makes a research on Floating Membrane Structure by Self-developed dynamic simulation system in the Visual Studio platform.The study on Floating Membrane Structure will revolve around representative example of Floating Membrane Structure-Floating Unit. The paper finds out profile shape of equilibrium of Floating Unit when the gravity effect is ignored, analyzes shift of each node of profile of equilibrium and the inner forces of rod for conformity to requirements through analysis of form finding and undertakes further research of gravity effect in the analysis of form finding.Based on the analysis of form finding, the paper makes research on load effect. By analysis of the stress state of structure under the effect of weight, snow loads and dynamic wind loads, the paper obtains a result related to displacement and internal force and identifies feasibility of Floating Unit applied to practical construction.Based on the principle of Cellular Automata, the paper analyzes Floating Membrane Structure, puts forward a new analytical method of Membrane Structure, enriches calculation and analysis method of Membrane Structure and has a developmental effect on analysis theory of Floating Membrane Structure. Feasibility analysis of Floating Unit provides theoretical basis for Floating Membrane Structure applied to practical construction such as sculpture, commercial advertisement, etc. It also gives an enormous impetus to Floating Membrane Structure applied to practical construction.
