ABSTRACT

In this research, surface moisture contents of columns and roof deflection of three Korean traditional timber houses were monitored. The monitored houses are composed of two different types of Hanok, that is, a one-story traditional Hanok built by traditional construction method, and two two-storied new-styled Hanok built by modernized construction method. The monitoring of traditional Hanok and new-styled Hanok1 has been carried out for about two and a half years, and that of the new-styled Hanok2 is 14 months. The monitored moisture contents were analyzed according to column location to the sun, wood types and relative humidity. The moisture contents of the northern columns are 0.71% higher than those of the southern columns, and moisture contents of raw wood was 0.83% higher than that of the glued structural wood. The mean vertical deflection of angle rafters is 11.6mm in traditional Hanok, 4.2mm in new-styled Hanok1 and 2.1mm in new-styled Hanok2. Meanwhile, the mean vertical deflection of plane rafters is 21.5mm in traditional Hanok, 9.7mm in new-styled Hanok1 and 20.3mm in new-styled Hanok2. Angle rafters and plane rafters showed meaningful deformations and that were affected mainly by roof weight and supporting member.
