Research On Folding Structures System And Static Force Behavior

Based on the basic principle of taxology and difference of construction feature, compositionality principle, working mechanism, the thesis research on generalization and classification of folding structures. On the basis of the study, the thesis gained computation model and computing method of folding structures system and found ;theoretical fundamental of folding structures analysis by using discretization processing, which is order to provide academic guarantee on program of folding structures theoretical analysis.The thesis provides wind force coefficient that is fit for vaulted folding structures and found wind load design calculation formulae, which is based on wind tunnel experiment of large-scale vaulted folding structures and take structure durable years, degree of safety etc into account.Aiming at folding structures particularity that roofing material is flexural membrane, the thesis found wind load design calculation formulaethat is fit to folding structures, which is based on structure life length, structure foldable degree etc and take account of snow distribution regularities, snow bag effect , snow cover excuraion and slippage.Using structure fault mode and finite element analysis software, the thesis arrive at a conclusion that the effect of initialization structure fault on ultimate bearing resistance of vaulted folding structures, which is based on full-scale folding reticulated shell tent structures research and perfect state theoretical analysis.
