摘要: Quasi-brittle materials such as concrete suffer from cracks during their life cycle, requiring great cost for conventional maintenance or replacement. In the last decades, self-healing are developed which capable of filling and healing regaining part stiffness strength automatically after getting damaged, bringing possibility maintenance-free structures. In this paper, a time dependent softening-healing law quasi-brittle is presented by introducing limited material parameters with clear physical background. Strong Discontinuity embedded Approach (SDA) adopted evaluating reliability model. numerical studies, values firstly obtained back analysis experimental results beams. Then models regarding members structures built non-healing simulated compared showing capability material.
