Steel-Concrete Composite Curve Of The Ramp On The Overpass Design

Steel—concrete composite structure is in steel and reinforced concrete structures developedon the basis of a new type of structure．It is rational use of high tensile strength of steel andconcrete in compression was achieved．Compared with the concrete structure,can reduceweight,reduce the earthquake,reducing the beam height,and enhance the landscape structureeffect,reduce the base cost,shorten the construction period．Compared with steel,which cailreduce the volume of steel,lower construction cost,increased stiffness,increased stability．Fromthe steel-concrete composite structure in Europe and Japan in recentyears the development andapplication of Our part of the bridge of view,it combines the advantages of steel and concretestructure,with high economic and technological benefits and social benefits,will become animportant direction for the development of structural systems．In recent years,with the rapid development of China。S modernization drive,thetransportation industry thrived,highways,overpasses and viaducts growing cities,promoting alarge number of oblique,curved appearance ofthe bridge．Curve of a concrete girder steel bridgewith its graceful CBrVes,and good adaptability to the road as well as its ability to leap,havebecome an impo~ant traffic engineering bridge．The lack of specific norms,the curve of aconcrete composite steel bridge design guidelines often are not designed for such information,orincomplete or non-existent dilemma．Therefore,these data complement and research imminent．This paper introduces the steel—concrete composite structure and development ofbroad andcurvedbridge designand constructionproblemsandthe rationaluseoffinite element softwaretoanalyze a mixed combination of curved steel girder bridge in question；then on the curved bridgethe computational theory and practical calculation methods are described,highlighting thepractical engineering of a three-span continuous curved steel girder bridge of a concrete finiteelement modeling method and related theory；Finally,the impact force curve characteristics ofbridge-related factors were research and draws some valuable conclusions...
