Nowadays, public’s interest to the traditional Korean house - Hanok - is widely increasing. Along with traditional Hanok, new traditional Korean-style house, which inherits classical grace and dignity and modernized for contemporary men and women, is gradually popularized. In this article, we are going to study the characteristics of structural analysis and design of Hanok. To perform structural analysis on Hanok, idealization of members, supports and connections should be preceded. Most structural members of Hanok are long compared to their section size, so they can be idealized as line elements. In Hanok, the connection points between column and foundation stone are considered as supports, and these supports are theoretically roller supports. But column supports have much friction and sometimes they have steel reinforcement so practically it can be more proper to idealize them as hinge supports. Connections between structural members in Hanok were generally framed by interknitting not using steel reinforcement, but nowadays in new traditional Korean-style house they are sometimes framed by steel reinforcement. Theoretically these connections can be idealized as hinge connections. But practically, in Hanok, column heads are firmly interknitted and suffer much pressure from heavy roof loads, so it would be better to consider them to have somewhat rotation stiffness. Meanwhile, rafters are simply laid on the purlins, so the connection between them can be idealized as using compression-only members. The strength of timbers is much influenced by the environmental factors and their sizes. So, modification factors should be applied to the basic allowable stresses to compute design allowable stresses. For all structural members, stress checks should be performed to all member forces, such as, axial force, shearing force, bending moment and combined forces. If stress checks are satisfied, serviceability check for deflection and vibration should be performed. The numbers of structural members are so many and they are framed so complicated, therefore it is very hard to model them in structural analysis software. To cope with these difficulties, the research group founded for the development of Hanok technology is now developing software which performs structural check of every single members of Hanok more easily and practically. Along with this software, they are also developing section tables for main structural members of Hanok, where engineers can find appropriate member size in their early design stages. When these researches are completed and the results are practically used, we can expect that they can help to propagate Hanok with safety and serviceability more widely. |
