The Exeperimental Study And Reliability Analysis On Two-way Slabs Reinforced With CFRP

Outside carbon fiber composite (carbon reinforced polymer, abbreviation of cfrp) reinforced concrete structure for a stronger fortified begins in the1980s, the construction and strengthen the clearance have little impact on the structure and cfrp itself has a strong light, and into a merit, and made it widely applied. So far, the researchers for the new mode of technology made more theory research, however, existing research are mostly concentrated in Beam strengthening after the fight cut performance, resistance and performance and strengthen the fight cut after the performance, vibration, the performance of reinforced concrete two-way board cfrp cloth reinforced by after the performance is still not mature research, given the bend the rules of the units to strengthen the method is not suitable for bidirectional board.The outside of cfrp cloth reinforced concrete structure for a stronger fortified theory research obvious lag in practice, how to use cartons for the two-way board to evaluate the performance has become a pressing need to resolve the issues. This article mainly of cfrp cloth reinforced by the load to bear all the role of reinforced concrete jane is a two-way board Bearing capacity the pilot study, the plastic the theory put forward the line to strengthen the capacity of calculation formula, finally, the formula had a reliable for the analysis, the paper is divided into four parts, the specific content of the following:1.A pilot study:Test produced a total of four pieces of the same specification of reinforced concrete two-way, including a comparison, three pieces of reinforcing the prime measure to strengthen and reinforce effects. to achieve and the actual construction to reinforce the cartons, in front of a split. the two boards in engineering applications are more loads to the experiment by static passed on both the load carried out. the simulation2.Test results within:Board and the analysis of cfrp reinforced and pulling by prior circumstances in which the gage to be measured. the phenomenon, and by the data for statistical analysis, the loading curve-change relations.3.Theoretical analysis: Use of plastic the model to adopt flexible line of the theory of the line of reasoning to strengthen the formula and calculate the theory with data on a comparative analysis.4.The finite element analysis:Ansys a model for the use of finite element numerical analysis, the finite element analysis as a result, the calculation, the value of contrasts.5. Reliability analysis:Using the monte carlo method based on the Matlab software applications for strengthening the capacity of the board corresponding formulas reliability analysis.Through the pilot studies and theoretical analysis, in conclusion, the use of cfrp1.A cloth reinforced concrete two-way to reinforce can significantly improve the board, resisting the crack of the performance and resisting deform ability, is an effective method, to strengthen2. CFRP cloth reinforced two-way board of the final form a cut at all, the difference is to load the localized events cfrp cloth is happening in divesting Loading area the destruction of the five ", and are under the load is in divesting cfrp cloth, the panel of a sharp decline in the area after loading the overall destruction, so cut down in the end of the department of cfrp appropriate fixing of reinforcing effect.3.The intensity of cfrp cloth reinforced for ten times, it’s very difficult to make full use, the linear volume increased cfrp cloth does not make the plate of linear high, so in the same area of cfrp cloth and pasted to strengthen the presence of an economy with the rate of the problem lies open to further study.4.The use of plastic the line to strengthen the maximum theoretical calculation Bearing capacity, the results of calculation is better than experiments, we are in safety.5. Through this paper reliability theory calculation and the traditional AFOSM method of the calculated value of contrast, the value is in no more than5%. the difference, and further strengthen the effectiveness of the approved plan.
