Development of Automatic Compression Test Method of Concrete Specimen using Source Location System

为了评价混凝土的断裂特性和局部化效应，采用反馈控制试验方法对混凝土试件进行了单轴压缩试验。根据试验结果，提出了混凝土受压应变软化行为的两种数值模型。通过与实验结果的比较，验证了所建模型的准确性。

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.
