초록

Amid the current trend of durability design toward a shift from the specification-based design to performance-based design of
concrete structures, quantitative grasping and detailed modeling of their deterioration mechanisms are demanded. It is essential to
accurately predict the moisture condition in concrete in response to the environmental conditions for ensuring the durability design
of concrete structures. The coexistence of moisture transfer and heat transfer in actual concrete structures requires consideration of
the effect of temperature on the moisture transfer, but few study models have examined moisture transfer under temperature
gradient. Accordingly, the purposes of this study are the formalization of mathematical model to predict temperature and moisture
distribution in concrete by any environmental condition and the construction of analysis technique, which are based on Maruyama's
pore structure model and Philip-De Vries' model about heat and moisture transfer analysis in porous medium. Verification results
with experimental data showed that the proposed FEM analysis method can simulate moisture behaviors under various temperature
and moisture conditions.
