| Abstract |
This study classified a detailed category of a line-type Hanok based on its plan type, spatial layout and evaluated the torsional irregularity of
this line-type Hanok. The line-type Hanok was classified into seven categories: perfectly symmetry, partial asymmetry, partial protrusion,
single open corner, complex, elongated rectangle, and multiple open corners. There were 22 cases of line-type Hanoks evaluated on torsional
irregularity; the results revealed that 21 cases belonged to torsional irregular and only one case belonged to torsional regular. The
X-directional average eccentricity ratio for all seven categories exceeded 100%. Among them, the perfectly symmetry type reflected the
smallest value of 105% and the multiple open corners type showed the largest value of 484%. The Y-directional average eccentricity ratio of
multiple open corners type was found to be 119%, which is larger than 100%; the remaining six types showed less than 100%. It is
anticipated that the results of this study can be utilized on initial seismic design and seismic evaluation of existing and newly built Hanok. |
