Research On High Performance Ferrocement Application In Reinforcement Of Concrete Girder Bridge

High performance Ferrocement is composited of Ferrocement by for the formation of grass-roots network of thin-layer reinforced composite sheet, with high toughness, ductility, durability and crack resistance, is an ideal material being applied to the area of reinforcement.According to existed results, my achievements are described as follows:(1) Fully Syria mortar reinforced composite high-performance networks, as well as the development of reinforced concrete beam design principles, with the double-layers ferrocement in middle and edges parts, improving the structure of the resistance, with the same size of single-layer, enhance the quality network of reinforced concrete structure.(2) Take full tension of ferrocement,using the 7.2m-span simply supported beam (b = 250, h = 600) model as an example, with ANSYS for refinement of the structure of double-layers, compared with Ltao.P beam B3 Test results, improving effective resistance, reducing the structure of the deflection of ferrocement to play a certain extent stripping.(3) Reviewed the structure of Shahe Yumin Bridge resistance, analysis the reasons of insufficient resistance, high-performance mortar reinforced composite reinforcement to mprove the resistance effect, and proposed monitoring requirements.Study on High performance Ferrocement of large-span continuous beam, generalized the application in stengthing fields and gives some actual guidance, as well as supply the direction of further research.
