Design And Research On Construction Technology Of ManJiang Steel-Lightweight Aggregate Concrete Composite Beam Bridge

Steel-concrete Composite structure is at steel structure and reinforced concrete structure foundation up develop of a kind of new structure.Compared with the reinforced concrete structure can ease self-respect, let up an earthquake function, let up a Gou piece piece noodles size, increase valid usage space, lower foundation to build price, economical the mold work preface and template, shorten construction period, increment Gou piece and structure of ductility etc..Compared with the steel structure can let up to use amount of steel, enlarge just a degree, the increment stability and whole, strengthen the structure anti- fire and enduring sex etc..In recent years, the combination structure of the steel-concrete at our country of applied fulfillment express, it and have the advantage of steel structure and concrete structure, have the technique economic performance and social performance of show the Zhao, in keeping with our country the state of the nation of the capital construction, will become structure system of important development one of the directions.The light bone which appears in recent years anticipates concrete, lightly common concrete because of its quality light, have in constucting bridge very strong of applied value.Is applied it in combining beam bridge, can consumedly ease bridge self-respect.Steel structure design the norm steels-concretes of the GB50017-2003 of our country rightness combination beam of design give design provision, the norm included exploitation to cut the design calculation of the noodles Su loading dint a method.For Nao degree calculation, rule the influence that Jian3 Zhi Liang2 wants to consider that shearing a slip of dint piece moves to transform.For the steel-concrete combination beam bridge of concretely start construction craft didn't give the detailed introduction, also didn't guide a sexual construction method for .Don't even involve for steel- light bone anticipating design method and construction craft of the concrete combination beam bridge.Lead these currently local steel structure design norm all involved of the problems all cause local steel-the light bone anticipate the concrete combination beam bridge to can not get a full application.Become a steel-the light bone anticipate the concrete combination beam bridge the bottleneck of the development.Need to the steel urgently currently-the light bone anticipate the design method of the concrete combination beam bridge to carry on induce, to the steel-light the bone anticipate a concrete combination the construction craft of the beam to carry on a thorough research and become to have engineering instruction the mature theories of the meaning thus.Therefore, to the steel-the light bone anticipate the research meaning of the design and construction craft of the concrete combination beam bridge a graveness.Aim at above not enough, this text carries on overall treatise and tallies up to the design method of combination beam up the foundation read in a great deal of cultural heritage, through a light bone anticipate concrete experiment, to the steel-light the bone anticipate the concrete combination beam bridge to carry on thorough of experiment a research.Rely on the Man river's steel-the light bone anticipate the design mission of the concrete combination beam bridge and mainly openned an exhibition a following research work:(1)In reading the foundation of a great deal of collection, summary and the overview existing steel-concrete combine the calculation method of loading dint and Nao degree of beam bridge and give the steel-concrete combine the design method of beam bridge and concrete step.(2)Anticipate the material function of concrete to carry on to the light bone indoor experiment a research, measurese various material index signs that the light bone anticipates concrete, for the steel-light the bone anticipate the concrete combination beam bridge's design to provide material parameter.(3)With the Man river's steel-the light bone anticipate the concrete combination beam bridge engineering for background, adopt a textual design method, carry on a detailed design to this bridge.(4)To the steel-the light bone anticipate the construction craft of the concrete combination beam bridge to carry on a thorough research, for the Man river's steel-light the bone anticipate the concrete combination beam bridge of the construction provide theories instruction.
