Battened Corrugated Steel Web PC Girder Bridge Of Statics Performance Study

Corrugated steel web PC combination box girder bridge is in the early1980s a new kindof composite structure bridge, it has the advantage of light deadweight, prestressed highefficiency, short construction period, beautiful shape, and many other advantages, At the sametime, its unique structure form that each component of structure stress clear. At present, thecorrugated steel web PC combination box girder bridge in our country also show a boomingdevelopment prospect, its application range is gradually to change section and large spanbridge expansion, the structure is more complicated. At home a nd abroad and the waveformsteel bridge maximum span were less than160m, single box single room bridge width are lessthan17m, But as the bridge span increases or bridge width will increase, single limbcorrugated steel web may be unable to meet the full requirements. So some experts raisedbattened corrugated steel web PC combination box girder bridge concept, therefore, the studyof battened corrugated steel web PC box girder combination of mechanical properties is verynecessary.This essay takes a seat span length of300m for rigid frame bridge model, the double legcorrugated steel web mechanics performance. In the study single limb corrugated steel webbridge based on the analysis of the theory, and draws up the box girder structure, using largebridge special finite element software Midas Civil modeling analysis, mainly studies thebattened corrugated steel web PC box girder in combination of large span continuous girderbridge of the bending and shearing of statics performance, analyzes the model in various loadcombination conditions web stress control condition. On the double leg corrugated steel webbox girder in long-span Bridges the feasibility of using a system evaluation.This essay research work shows that the double leg corrugated steel web PC combinationof continuous box girder bending, shear, roof and floor crack, and other basic staticsperformance all comply with the design requirements. From model analysis that, due to theweb height is bigger, web control stress and not by steel plate shear strength control, but byweb synthesis buckling control, and through calculation, also can meet the requirements ofspecification, and a greater safety stock. Hope this research results for corrugated steel webbridge design and reinforcement, such as the provision of technical reference.
