This paper aims to analyze the results of compression tests conducted on fabric-reinforced cementitious matrix (FRCM)–confinedconcrete elements. The analysis is developed using a database of 152 compression tests on FRCM-wrapped, plain concrete cylindricalspecimens assembled from the literature. The database is first used to analyze the influence of the relevant mechanical and geometric parameterson the structural response of the confined specimens. Then, empirical design–oriented models to predict the peak strength and thecorresponding strain of the FRCM-wrapped specimens are proposed and verified with the experimental database through a best-fit analysisof the collected data. The performance of the proposed models is also compared to that of some existing models (which have been proposed inboth the literature and codes) by using the database

Abstract

This paper aims to analyze the results of compression tests conducted on fabric-reinforced cementitious matrix (FRCM)–confinedconcrete elements. The analysis is developed using a database of 152 compression tests on FRCM-wrapped, plain concrete cylindricalspecimens assembled from the literature. The database is first used to analyze the influence of the relevant mechanical and geometric parameterson the structural response of the confined specimens. Then, empirical design–oriented models to predict the peak strength and thecorresponding strain of the FRCM-wrapped specimens are proposed and verified with the experimental database through a best-fit analysisof the collected data. The performance of the proposed models is also compared to that of some existing models (which have been proposed inboth the literature and codes) by using the database
