A method to solve tension softening relationship of concrete obtained from a three-point bending test is presented.The method is based on the extended fictitious crack model,by fitting the theoretical calculated stress-crack width(Load-CMOD,P-CMOD)relationship to the experimentally determined P-CMOD curves to obtain the tensile softening relationship.All inputted parameters used in the calculation were directly obtained from the three-point bending test.The advantage of the present method is that the displa...
