The Korean traditional house, Hanok, is a post-and-beam timber structure with a large tiled roof designed to keep the house cool in summer (Fig. 1). The solid wood members are connected together without metallic connectors, using complex wood–wood joints, while the posts are fitted inside cornerstones. Associated with the stabilizing effect of the heavy roof, this provides a basic lateral resistance to the house, which historically proved effective against the few earthquakes which occurred in this area of low seismicity. Nowadays, the Hanok house is still fairly popular among Koreans thanks to its cultural, aesthetic, and eco-friendly aspects.
