Prestressed Carbon Fiber Sheet Reinforced Concrete Beam Of The Simulation Analysis

Prestressed Carbon Fiber Reinforced Polymer（CFRP）sheet reinforced concretestructures has been the frontier subject in the international civil engineeringconstruction and related fields.. Performance of FRP composite material is excellentin light weight, high strength, good corrosion resistance, reinforcement efficiencyhigher, and its construction is simple, short construction period and does not increasethe weight, highly in terms of component reinforcement engineering. Reinforcedconcrete structure is a main application form attached with CFRP sheet and stick onthe prestressed CFRP material in reinforced concrete beam of ramen noodles, cansignificantly improve the flexural bearing capacity of beam, the prestressing effect,can offset part of the initial load, reducing the original beam deflection, crack width inthe beam decrease or even closed, limit the emergence of new cracks, thus improvethe performance of normal use on the beam. For prestressed CFRP sheet is stuckoutside reinforcement way, make its and reinforce the object firmly together, form anorganic whole, is a very important aspect.FRP sheet anchored by WSGG is to prestress Carbon fiber sheet. The strength ofthe play is in advance,to effectively use the high strength properties. This methodseries multiple waveform anchor. First fixed ends, then tighte intermediate. Rely onintermediate anchor of clamping and fastening. Not only played a prestressedtensioning role, but also played the role of anchorage. Realize the carbon fiber withthe tension and anchorage integration construction. Using this technique, to save a lotof material and the engineering cost, reduce the reinforcement system maintenancecost; Drastically reduce the deformation of the structure, increase the bearing capacityof improved the stiffness at the same time; Inhibition of crack development, improvethe flexural bearing capacity of components. People have been constantly fortechnical improvement and perfect related system, and in vitro anchoring CFRP sheetis prestressing reinforcement technology is more simple, rapid and economy.The success of WSGG anchor for multi-point anchoring reinforcement concretebeam, can not only anchor prestressed CFRP sheet, carbon fiber put up and theprestressed is also more convenient and quick, thus well realize the structure ofexternal prestressing reinforcement. Because of CFRP sheet reinforced concrete beamfracture and crack extension, involves complex mechanical behavior, such asgeometric nonlinearity, material nonlinearity, and the high cost of test. Means it is difficult to observed using test interface under the internal micro cracks of concreteand extension process, to a large number of reinforced concrete structure analysisproblem, can only solve with numerical analysis method, the traditional analyticalmethod value also can solve the calculation problem of some very simple componentor structure. Finite element analysis method in the nonlinear analysis of reinforcedconcrete structures, as a powerful numerical analysis tool, has played a very importantrole. This paper studies the application of technology, and Da jian kou of Yong Chuanbridge,the bridge reinforcement application and evaluation. Da jian kou on the successof bridge reinforcement and the static load test proved that the prestressed carbonfiber reinforcement technology has engineering practical value. For the actual bridgeengineering application to lay a solid foundation.
