Canting Pull Steel Tube Concrete Arch Bridge Structure Statical Analysis

The design feature proceed know clearly systematic analysis of the text versus canting pull steel tube concrete arch bridge, it is above "joist type built-up arch bridge" architectural characteristic analytic foundation to said bridge type, certain technical characterstic point syntheses handle to oneness new bridge type among steel tube concrete arch bridge, stayed-cable bridge type.Direct to canting pull steel tube concrete arch bridge' s construction features, set for know clearly finite element analysis 'model, through the medium of flush joint compose under the action of dead load analyses, get bridge type monolithic construction with arch 'stress characteristic give priority to fairing; through the medium of continuous beam breakpoint flush joint compose impact analysis, the mount versus scale structural degree of statical indeterminacy, down of the derive breakpoint it is necessary to wane continuous beam ewe warm up change creative pull; the orthodox construction of the diagonal bar hereon breach joist type built-up arch bridge usually use stiff pole, adopt flexibility dragline, keep out of joist type built-up arch bridge stiff pole non-tunable whole hypogene shortcoming, succeed bridge queen could through the medium of optimize cable number cum cable force gotten arch ring each section pressure line departure proportion, the action of the preferable exert steel tube concrete arch, ensure bridge structure internal force distributive proportion against.Construction stage, said bridge type adopt "dead load zero bending moment" theory proceed construction control, through the medium of select appropriate cable forceful construction instrument came dam bridge altitudinal immovability back, construction course median cord forceful away adjust ensure know clearly bridge positional exactness, lead whole bridge stress all the more in reason to against.It is time for theses combine case history versus to bridge type proceed systemic statical analysis, both present know clearly finite element model and figure , look into harvest useful for ulterior canting pull steel tube concrete arch bridge 'design effort among.
