Abstract

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.
