Abstract
Dehumidification system h a box girder is the effective tool to reduce the LCC of bridges. The effectiveness of dehumidification system is examined in this study by applying Computational Fluid Dynamics (CFD) combined with transport equations of moisture and temperature to the flow inside a box girder. CFD evaluates that this system consisting of long ducts with small side holes is useful to reduce the total moisture and to avoid locally high relative humidity.
