摘要：Tension stiffening is a structural property of reinforced concrete that refers to the contribution ofconcrete between cracks to the overall stiffness of the member. In this study tension stiffening is experimentallyevaluated considering the variables like the diameter of reinforced steel and incorporation of metallic and non-metallicfibres which depends on many factors such as size, type, elastic properties, aspect ratio, and volume fraction of fibres.For calculating the crack spacing, CEB-FIP code provision was considered and compared with the values ofexperimentally tested tension stiffening prism specimen.The successful implementation of the tension stiffeningbehaviour is demonstrated through the prediction of deformation of reinforced steel as per uniaxial load using a generalnonlinear FE analysis package (ANSYS) by modelling and analysing reinforced concrete prism member.Based on thestudy,it has been found that the addition of fibres has increased the tension stiffening effect considerably.Crack spacingincreased and number of cracks and crackwidth were decreased with the increase in fibre content.
