An ideal elastic-plastic constitutive relation of concrete and masonry that can be applied to finite element analysis is deduced. This ideal elastic-plastic constitutive relation is applied to reinforced arch segment, numerical model is established by finite element software ANSYS and is checked by test. The result show that the finite element numerical adopted this ideal elastic-plastic constitutive relation of concrete and masonry is close to measured value, ultimate bearing capacity of the finite element numerical reduced by 6.8%—9.2% compared to measured value. The results show that an ideal elastic-plastic constitutive relation of concrete and masonry is reliable when masonry arch is strengthened by composite main arch circle method, this method can be applicable in the analysis of the same kind of bridge structures., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=4RpIOppgEGZIMmUHF6Ouxg==, pdfFileSize=1443578, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
