| Abstract: | specimens of steel fibre reinforced concrete under triaxial stresses are studied experimentally with the triaxial apparatus designed by the authors.The emphasis is put on the study of the characteristics of deformation. The stress ratiossubjected to the specimens include triaxial compression,biaxial compressionuniaxial tension, biaxial tension-uniaxial compression and triaxial tension. Thecharacteristics of the stress-strain relationship and the influences of steel fibre content and intermediate principal stress on the peak strain are analy--sed.The stress-volume strain relationships of steel fibre reinforced concrete under triakial stresses are discussed. |
