초록

본 연구에서는 한옥의 평면유형과 비틀림비정형의 상관성을 고찰하였다. 한옥 64채를 평면유형에 따라 분류하여 비틀림비정형 여부를 평가하였다. 평가결과, 일자형, C자형, □자형 한옥은 한방향, L자형, T자형 한옥은 두방향 비틀림비정형이 우세하였다. 각 평면유형별 최대편심비율은 일자형 565%, L자형 298%, T자형 362%, C자형 312%, □자형 211%이었다. 대부분 한옥의 편심비율은 X방향 100~300%, Y방향 35~200%에 분포하였다. 본 연구결과는 한옥의 내진설계를 위한 비틀림비정형 평가 가이드라인으로 활용될 수 있다.

This paper evaluated a relationship between torsional irregularity and plan layouts of Korean traditional timber houses, Hanok. The plan types of Hanok is categorized as straight-lined, L-shaped, T-shaped, C-shaped, and closed rectangular shape. Plan types of Hanok plays an key role in determining the centers of mass and the center of stiffness. Sixty-four cases of Hanoks categorized as five plan types, that is, 24 cases for line-type, 16 cases for L-type, 7 cases for T-type, 10 cases for C-type, and 7 cases for rectangular-type were evaluated on the torsional irregularity based on plan layouts by using the software developed by the authors. The results showed that the torsional irregularity in one direction (X or Y direction) was dominant in line-type, C-type, and rectangular-type Hanoks. On the other hand, the torsional irregularity in two directions (both X and Y directions) was dominant in L-type and T-type Hanoks. The maximum eccentricity ratio for each plan type is 565% for line-type, 298% for L-type, 362% for T-type, 312% for C-type, and 211% for rectangular-type Hanok, respectively. Regardless of the plan layouts, the eccentricity ratio of most cases is ranged 100~300% in X-direction and 35~200% in Y-direction. The results can be used as the design guide for checking torsional irregularity of Hanok in early seismic design stage of Hanok.
