Abstract

The purpose of this study is to find out the factors related to the recent roof collapse accidents of cultural heritage. The specimens were made in half shape of the roof and observed variation of load, temperature and humidity through real-time monitoring. After construction of the specimens, each of two specimens were dismantled at the time of 1, 2, and 4 months later to obtain the moisture content of soil and rafters. During the four months, the weight of the specimens decreased by 5.2%. Over time, the water content of the soil components tended to decrease, but the moisture content of rafters did not decrease. The moisture content according to the location of the rafters has a low moisture content from eaves to the beams, and has a high moisture content from the beams to the top. In the beam, the highest moisture content appears due to the construction of Dangolmak.
