Abstract
The current challenge in concrete drying simulation is quantification and modelling of its various theoretical mechanisms. The second author has developed a drying shrinkage strain model based on concrete microstructure, age and internal humidity. Validation of such a model provides insight into the validity of the assumed theoretical mechanisms. In this model, pore capillary tension is the main strain mechanism. Currently, application of the model to Japanese (JCMac) and European (DIANA10) finite element programs is under way.
This paper focuses on FE analysis results of the drying shrinkage model. It is programmed as a User Supplied Subroutine for the DIANA10 finite element analysis package. This places the model in the middle of the DIANA analysis, interacting with heat flow and structural analyses. Aside from applying the material model itself, special use of DIANA’s parallel heat analysis is required.
Initial results of the FE application are presented, showing promise and encouraging further development and research.
