Abstract

This research performed deformation monitoring for a Korean traditional wooden house called a Hanok to figure out its long-term deformational characteristics and hence, to establish basic data for the maintenance and management of Hanok. The monitored buildings are composed of two different types of Hanok, one is a one-story traditional Hanok built by traditional construction method, and the other is a two-storied, new-styled Hanok built by modernized construction method. The vertical deflection of roof structural members was measured for about two years. The mean vertical deflection of the angle rafter, called Chuneo, which is located on the corner of eaves, is 10.0mm in the traditional Hanok and 1.7mm and 5.7mm both in the new-styled Hanok's 1st and 2nd roof, respectively. The traditional Hanok showed 2~5times more deflection than the new-styled Hanok, and this result can be deduced from the fact that the roof weight of the traditional Hanok is 2~3 times more than that of the new-styled Hanok, so the traditional Hanok showed more long-term deflection than the new-styled Hanok.

Highlights

The Korean traditional wooden house is called a Hanok, and it has a history of over 2,000 years
There are small fluctuations in the graph, especially in the angle rafters of 2nd roof of the new-styled Hanok as shown in Fig. 4(c), the overall graph shows a gradual decrease as time goes by
This research performed deformation monitoring for the Korean traditional wooden house called a Hanok, to establish the basic data for the maintenance and management of the Korean traditional wooden house

Summary

Introduction

The Korean traditional wooden house is called a Hanok, and it has a history of over 2,000 years. Lee et al [5] performed shaking table tests on the 1/15 scale test model of both traditional and new-styled Hanok and compared their dynamic characteristics. Kim [9] performed monitoring of the moisture contents for both Korean traditional Hanok and new-styled Hanok for about one and a half years and analyzed the moisture contents on three criteria; namely, column location, wood type and relative humidity. Abroad, Kang et al [10] evaluated stiffness of the mortise and tenon joint in Chinese traditional timber structure, Lindt et al [11] performed shaking table test to evaluate seismic response of a six story light frame wooden building, and. To establish the basic data for the maintenance and management of a Hanok, the long-term deformation of both a traditional and new-styled Hanok were measured for about two years, and the deformational characteristics were analyzed
