Reinforcement And Elastic-plastic Analysis Of Reinforced Concrete Frame Structure

With the development of economy and society,the reasons as the transformation of the urban planning,building function,aging buildings,buildings damage,design standards improve or improper construction and need to reinforcement of buildings.At present,about carbon fiber and steel reinforcement concrete beams,columns and joints and so on member performance of more and have been relatively mature,and for the carbon fiber and steel common reinforcement research on the performance of the framework of the overall work is still relatively small.In this paper,the steel reinforced concrete frame,which is made of carbon fiber and steel,is strengthened and finite element analysis.The main research contents are as follows:(1)The quality of the main structure of a building structure identification,to be completed in the building reinforcement conclusion,after considering the advantages and disadvantages of various reinforcement programs and field factors,to determine the reinforcement method: paste carbon fiber reinforced beams,reinforced steel reinforcement column.(2)The reinforcement of the beam and the column in the frame structure is determined,the reinforcement parameters are selected and the reinforcement technology is obtained.(3)The finite element analysis model of beam-column single-member is established,and the static and elastic-plastic analysis is carried out.The deflection and lateral displacement of the beam after reinforcement are obtained.The deflection of beam obtained 13%,the lateral displacement of the column obtained 30%.(4)The static structure of the frame is analyzed,and the results show that the stress,strain and seismic response of the structure are obtained after the reinforcement,and the performance of the reinforced frame structure can be obtained,which can provide the basis for similar projects in the future.
