Non-linear finite element analysis of the flexural reinforced concrete beam strengthened with CFRP sheets

ZHANG Lei~1,XUE Yong~2,DING Hong-yan~1(1.School of Civil Engineering,Tianjin University,Tianjin 300072,China;2.Tianjin Real Estate Appraisal Survey and Design Institute,Tianjin 300320,China)  
This paper utilizes ANSYS,a finite element analysis program,to set up the non-linear finite element model of concrete,and analyze the whole flexural process of the cross-section of the RC beams strengthende with CFRP.The paper actualizes the structural initial load using the element birth and death technology,and contrasts the RC beam strengthened with CFRP on the bottom face with the one strengthened with CFRP on the side faces.The results show:The intensity and rigidity of the RC beam strengthened with CFRP on the side faces comparing the one strengthened with CFRP on the bottom face drop very much little,and the RC beam strengthened with CFRP on the side faces has better ductility and deformability.Finally,the paper compares ANSYS analysis results with the theoretical results calculating in term of "Technical Specification for Strengthening Concrete Structure with CFRP",there being a good match between both.The conclusion indicates that the ANSYS analysis is feasible and credible.
