The Endure Strength Capability Investigate Of The Girder's Positive Section Which Complex Reinforced With The Prestressing Force CFRP And Armor Plate

The reinforcement work of new and old building is our country major work. our country many building may have security issue in our country,so we must do more and more reinforcement work.the appraisal bulletin become major gist when government deal with building dissension.The prestressing force CFRP reinforce technic which become be regarded in building engineering domain has many excellences in recent years.More and more colleges and scientific research institutions research this reinforce technic and acquire a great deal research productions.This technic is applied in Many projects,many expert deem this technic fit reinforcing building.The prestressing force CFRP reinforce technic has many excellences, which have been applied in reinforce project. It is a in dire need of problem how in effect bring to bear prestressing force to CFRP.Many domestic research institutes have done in the gross work and acquired in the gross productions. At the present time,a majority of domestic anchor tools just adapt to use in laboratory,which is not adapt to use in project.we refer in the gross datas to empolder adapt to use in project.we empolder revolving model anchor tool through a great deal test.CFRP reinforce technic is a new technic which is daub glue in order to all together work with concrete girder. The concerned research datum show that CFRP is not demolish when girder destroyed time.Many researcher give their attention to the issue how bring into play the CFRP tall intension capability.we bring forward the reinforce means which is affix prestressing force CFRP in girder pull area and armor plate in girder Drang area.This test is sustained by academician science and technology innovation item of Tai An. This test design 5 girders which is reinforced base in design project.we gained the girder dynamo capability by analyzing test data. The girder which is complex reinforced dynamo capability have more advanced compare to common girder and crack develop less breadth.At last,we obtain exoterica result which is corresponding with test data base on concerned research datum.
