| 1 | Description of Concrete Durability Damage Process显示文摘Based on the damage mechanics, the concrete damage grade of relative stable environment in measurable spatial is constructed in this paper, and the concrete damage evolving model and corresponding failure rule is constructed based on the damage grade fore-defined. Therefore, the concrete health status and the residual life-span can be assessed according to the measured damage grade. It is propitious to drive the development of concrete durability assessment and life-span forecast. Its feasibility of concrete damage process description and health assessment is validated with the example in this paper, in which the damage state is described with the ultrasound velocity attenuation, and the freeze-thaw process is regarded as the concrete durability degradation influencing factor to reflect the concrete durability degradation process. | CHEN Yueshun WEI Jun ZHAO Xiaolong | 2006 | Wuhan University Journal of Natural Sciences2006，11，3： | 1 |
| 2 | Elasto-Plasticity Critical Corrosive Ratio Model for RC Structure Corrosive Expanding Crack显示文摘The parameter of filling expanding ratio n, plasticity factor k1 and deformation parameter k 2 is raised, and then the elasto-plasticity critical corrosive ratio model for RC structure corrosive expanding crack based on elasto-plasticity theory is constructed in this paper. The influences of parameters such as filling expansion ratio n, plasticity factor k1 , deformation pa-rameter k 2, Poisson ratio of concrete v, diameter of reinforced bar d and protective layer thickness c on the critical corrosive ratio are researched by theory analysis and experiments. The experimental results validate the accuracy of the model. According to the ex-perimental study, the least squares solution is calculated as n = 1.8, k1 = 0.61, k 2 = 0.5. | CHEN Yueshun LU Yiyan LIU Li | 2007 | Wuhan University Journal of Natural Sciences2007，12，6： | 0 |
