| Research Abstract |
The multi-scale simulation model to quantify the micro damage of cracked/uncracked cementitious composites as well as structural performance made by massive concrete was developed. The model is capable of successfully simulating a long-term behaviors of concrete structure subjected to repeated thousand～million cycles of loads in its life. Furthermore, ion resolution from concrete, such as calcium, boron etc. and re-absorption model for underground concrete structure was provided. With coupling the macro and micro models, this study enables to predict long-term mechanical and thermo-dynamic performances of structural concrete and its environmental impact.
