  • Descrição: The application of steel fibre reinforced concrete (SFRC) isconstantly increasing. However, due to the absence of universallyaccepted guidelines for SFRC, the application fields of this materialare still limited. Post-cracking load carrying capacity is aproperty of concrete most benefited by steel fibre reinforcement,usually designed by the residual strength of SFRC in tension, ffr.However, the quantification of ffr is one of the most critical issues.The research reported in this paper is dedicated to determining theresidual strength of SFRC in tension. The experimental results often notched beams with the fibre content of 0.5% and 1.0% byvolume subjected to a three-point loading scheme are presented.Considering SFRC as a homogeneous material, a mechanicallysound method for the inverse analysis of SFRC was proposed.The adequacy of the calculated results was validated using experimentaldata on standard flexural specimens. Computationaleffectiveness was proved employing derived residual strengthmodels into the nonlinear finite element analysis program. [PUBLICATION ABSTRACT]
