| Research Abstract |
To evaluate the fracture properties and localization effects of concrete, uniaxial compression tests of concrete specimens were conducted using feedback control test method. Based on the test results, two numerical models of strain softening behavior of concrete in compression were proposed. The accuracy of the proposed models was illustrated by comparing the behavior of the models with the results of experiments.
