Experimental data0 vMechanics of Composite Materials, 42(1), p.13, 20063 aThe results of a comprehensive test program for the mechanical behavior of round concrete specimens confined by carbon-fiber epoxy tapes and prestressed carbon yarns are reported. Five different concrete batches of compressive strength from 20 to 100 MPa and the confinement of various thickness and pretension level were investigated. The specimens, which were subjected to monotonic or repeated compressive loadings, showed a nonlinear stress-strain behavior with a significant ductility and increased ultimate strength, in contrary to the brittle behavior of plain concrete. The limit of linearity on the stress-strain diagrams of the confined concrete roughly coincided with the ultimate strength of plain concrete. Above this limit, the damage accumulation and plastic deformations proceeded in the confined specimens. This fact was evidenced by the increasing slope of deformation diagrams in unloadings and repeated loadings and by the pronounced residual strains. The limit of linearity could be raised significantly by pretension of the carbon yarns during their winding.14aCONCRETE14aCYLINDRICAL SPECIMENS14aCOMPOSITE CONFINEMENT14aCOMPRESSIVE LOADING14aPLASTICITY14aDAMAGE14aSTRENGTH12aTamuzs, V.12aTepfers, R.12aYou, S.C.12aRousakis, T.12aRepelis, I.12aSkruls, V.12aVilks, U.40uhttps://drive.google.com/file/d/1MIOQS8qqm5I78LMlEMQi9EdTH25ww4Nd/view?usp=drivesdkzPara ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx250602s9999 xx |||||s2 |||| ||und|d
