| Abstract | ||
| Abstract Experimental investigation is carried out to study the shear transfer of uncracked fibrous concrete. The test specimens used in this study were of the push-off and modified push-off type .The parameters investigated were the volume fraction of fibers, the amount of stirrups crossing the shear plane, and the ratio of direct to shear stress. Test results showed that the presence of normal stress and fibres increase the first cracking load and shear transfer strength and this enhancement is more pronounced in specimens without stirrups in the shear plane for both push-off and modified push-off specimens. The fibrous specimens showed more stiffness, failed in a ductile mode, and experienced more strain capacity than plain specimens without fibres. From the present test results, a regression analysis was done and a prediction formula is proposed .
