Recently, ultra high performance fiber reinforced concrete (UHPFRC) has been developed to attain considerably increased\ncompressive cracking strength and ductile tensile behavior with high tensile strength through adding straight steel fibers in concrete\nmixture. Although benefits with UHPFRC were investigated through experimental program, it is difficult to predict structural\nbehavior ofUHPFRCmembers since theoretical approaches are limited. In this paper, inverse analysis procedure has been proposed\nfor a three-point bending test with notched UHPFRC beams so that tensile behavior of UHPFRC could be rationally evaluated.\nOn the inverse analysis procedure, failure mode of the UHPFRC beam was simplified and the simplified diverse embedment\nmodel (SDEM) was employed. To verify the proposed inverse analysis procedure, UHPFRC beams with a notch were analyzed\nwith the tensile behavior of UHPFRC evaluated through the inverse analysis procedure. The analytical predictions showed good\nagreement with the load-crack mouth opening displacement (CMOD) responses measured through the three-point bending test.\nConsequently, it can be concluded that UHPFRC tensile behavior can be rationally evaluated through the proposed inverse analysis\nprocedure.Theproposed inverse analysis procedure can be useful in relevant research areas such as development of advanced design\napproaches or computational methods for UHPFRC members.
