Load–deflection performance of partially prestressed concrete T-beams with steel fibres in partial and full depth Available to Purchase

A total of twelve partially prestressed concrete T-beams were cast without and with fibres in partial and full depth. These beams were tested to assess the effect of fibre addition in different zones in the cross-section, namely, flange, web or the entire cross-section, on the load–deflection performance of the flexure critical beam specimens. An attempt has been made to predict the load–deflection characteristics of the beam specimens utilising the tension softening effects in the stress–strain behaviour of fibre-reinforced concrete. The proposed model accounts for the interaction of the matrix with the fibre pull-out mechanism. The details of the constitutive material properties used and the proposed layer-based analysis are presented in this paper. Comparisons with test data show good agreement.
