چکیده
To perform the assessment of reinforced concrete infrastructures in service, a multi-scale simulation has been developed and improved with an integrated hygro-thermal-chemo-electrical-mechanistic approach. Various durability issues are successfully evaluated terms fatigue behaviours damage induced by moisture motion through pores cracks, temperature-related deterioration such as frost/fire damage, degradation chemical reaction like alkali-silica reaction, macro-cell corrosion coupled multi-ion equilibrium which is electro-chemical phenomenon. Moreover, long-term performance evaluation influenced drying shrinkage also conducted. Furthermore, approach AI technique data assimilation techniques. The crack locations their widths converted to space-averaged strains, built inside cyber storage for futural prediction. hazard map patterns on surface deck inversely derived from artificial neural network, according big dataset past maintenance records. Through both methods, importance using both-eye diagnosis realized proposed lifetime structural concrete.

A poroplastic model for hygro-chemo-mechanical damage of concrete
The paper proposes an analytical model for calcium leaching of concrete due to water. The model is set in the framework of chemically active saturated porous media. Continuum damage mechanics is used in order to develop a phenomenological poroplastic model of concrete. Two forms of damaging processes are included: mechanical, modelled with two scalar damage internal variables; chemical, related...

Abstract—The degradation of concrete due to various hygrochemo-mechanical actions is inevitable for the structures particularly built to store water. Therefore, it is essential to determine the material properties of dam-like structures due to ageing to predict the behavior of such structures after a certain age. The degraded material properties are calculated by introducing isotropic degradati...
متن کاملA Numerical Simulation Approach to Calculating Hygro- thermal Deformation of Concrete Based on Heat and Moisture Transfer in Porous Medium
Concrete deformation due to temperature and moisture condition will always develop simultaneously and interactively. The environmentally (hygral and thermally) induced stress and deformation are essential to concrete durability. To simulate the deformation of concrete caused by the coupling effect of temperature and moisture, a numerical simulation approach is proposed comprising analytical pro...
