Abstract:

As the softening constitutive relation of concrete basic fracture properties (softening curve), limited by the current level of experimental techniques, the test methods of softening curve such as direct tension tests and so on are difficult, high cost and different outcomes, so the study is difficult to move forward. In recent years, the inverse analysis study which uses numerical methods to determine the softening curve based on simple fracture test has emerged. The author combines concrete direct tensile test and the whole process of inverse analysis by numerical method, which is engaged in many years, and discusses the new ideas for solving the softening curves by using of computer technology to select the optimized method. The softening curve obtained by inverse analysis with the thinking of programming and the curve obtained by experiment are in line within the range of allowable error.
