Abstract

In order to propose measures for the future preservation of the interior of Hagia Sophia, it is necessary to clarify the causes of deterioration. In the present study,thermal imaging and moisture content distribution measurement were conducted during fieldsurvey in September 2012. Moisture transfer in the wall was analyzed by using the indoor and outdoor temperature and humidity measured in September 2010. In addition, the appropriate time to cover the outside wall in order to prevent evaporation of accumulatedwater at the inside surface of the wall was examined by numerical simulation. The main results obtained are as follows.1)From the measurement of moisture content, it was found that the wall in all directions of the second cornice has moisture content of more than 20%. Especially the northwest side of the indoor wall surface of the second cornice has the highest average moisture content.2)The location of water flow on the wall can be identified from thermal image survey. At the location of the water flow, there is large peeling of the mortar joint.3) Numerical simulation shows that moisture content of the inner wall surface rises because of the penetration of rainwater at the outer wall surface.4)Numerical simulation shows that appropriate time to cover the outer wall is summer because the moisture content in the wall then is lower than in the other seasons.
