Detection And Reinforcement Of A Station In Shenyang Of The Reinforced Concrete Frame Structure

ABSTRACT: At present，most of the buildings in China are reinforcedconcrete structure,due to their own aging, a variety of natural disasters and man-madedamage and other reasons, the continuous generation of a variety of buildingstructural safety problems.Therefore, the existing building structure detection, repair,einforcement and reconstruction is generally the focus of the world. In our country,the reinforced concrete frame structure detection, repair, reinforcement andreconstruction research started relatively late, the existing structure of the safetyassessment standard is not perfect. Therefore, further research on hand detection,reinforced concrete frame structure repair, reinforcement and reconstruction is verynecessary. At the same time, the development of detection and identification ofstructural reinforcement technology to positive effect on improving the quality ofconstruction, saving the country and the enterprise funds and guarantee the enterpriseproduction safety and so on.This article from the reinforced concrete frame structure of the qualityrequirements, the detection of reinforced concrete framed structure and content, andsummarized the detection methods of reinforced concrete frame structure; Also onthe reinforcement of the stress of structure of scientific analysis, expounds thestructure reinforcement procedures; Then the reinforced concrete frame structure ofthe main reinforcement techniques such as increasing section method, steelreinforcement method, external bonded steel reinforcement method, sticking carbonfiber were introduced in detail.The author combined with the reinforcement of their participation, strengtheningdetection, concrete frame structure is analyzed, and combined with the engineeringcharacteristics of the reinforcement method with carbon fiber cloth, and through thecalculation of the frame beam, column for further study of the reinforcement method; At the same time, the carbon fiber reinforced method construction technology,have certain reference to the reinforcement of reinforced concrete frame structure.On the mechanical properties of carbon fibre reinforced concrete beams wereanalyzed by the nonlinear finite element analysis using ANSYS software, Through thereinforced and unreinforced beam of finite element results comparative analysis canbe drawn: Strengthening the bearing capacity can be significantly increased, bendingbeam in addition, compared with the unreinforced beam, in the same load, thereinforcement beam deflection than the unreinforced beam decreases obviously, crackand width, stiffness increased, these at home and abroad to do the experiment result isconsistent.
