| 要旨 |
The numerical method to evaluate the cracking behavior induced by hydration reaction in mass concrete was developed. The method is combined with structural and heat transfer analysis，in which the Rigid-Body-Spring Model (RBSM) is used as a basis of a structural model and truss network model is utilized as heat transfer model. The solidification concept depending on time is applied to the constitutive model of concrete before and after cracking. For the application model (wall structure), the structure behaviors show the reasonably correspond with real structure. |
