Experiment And Theory Analysis Of Behaviour Of Concrete Beams With Part CFRP-PCPs Bars

In recent years, with The carbon fibers (Carbon Fiber Reinforced Polymer, CFRP)reinforcement material of design theory and construction technology of maturedeveloping,It has gradually become the ideal substitutes of reinforcement. And it hadapplied to the practical engineering. This paper put forward concrete beams with partCFRP-PCPs; This concept can avoid the cumbersome process of tension. And Compositereinforcement as a kind of priestesses bars can effectively storage priestesses, so that wecan product composite reinforcement in bulk. It can effectively shorten the constructionperiod. Concrete beams with part CFRP-PCPs place the CFRP-PCPs bars in force (across)the most unfavorable position and take the most unfavorable region length (pure bendingsection). The method can avoid unnecessary waste, improve the utilization rate of thecomposite reinforcement, the optimum design can be economically.This article with the help of the national natural science fund project(51168006).This paper based on the force behavior of CFRP-PCPs composite reinforcedthe zetetic experiment research. Its performance in the past on the basis of furtherperfecting the main research work is as follows:(1) Summaring and analysising the mechanical performance of the compositereinforced CFRP-PCPs, its properties have certain cognitive and then study the nextresearch direction and focus.and put forword the saying “concrete beams with partCFRP-PCPs”.(2) based on Part with CFRP-PCPs concrete beam composite reinforcement stressperformance test research, considering the different cross section of compositereinforcement, as well as the number of different composite reinforcement for compositereinforcement is placed in the different tension control on the basis of prestressed CFRPtendons, Studing the process of component force, failure process and ultimate bearingcapacity, crack and deformation characteristics of experimental research.(3) Through the test data, and combined with the current specification, the localcharacteristics (cracking load and ultimate load) of composite reinforced concrete beamswith part CFRP-PCPs; Calculating the deflection and Crack. Finally the experimentalvalues are close to the theoretical calculated results.(4) According to the nonlinear finite element simulation that the local stress of thecomposite reinforced concrete beams with part CFRP-PCPs behavior experimental, wihtthe limited test artifacts getting more experimental datas, and validate the result of the test.
