This paper is aimed to clarify the type and its characteristics of wooden roof truss in modern age of Korea focused 64 architectural properties. These are largely classified with traditional korean and japanese roof structure, western king and queen post roof truss, and so on. The roof structure of korean architecture have been evolved into combining traditional wooden structure(rafter) with wooden roof truss. Korean carpenters have tried to improve wood structure by using the principal rafter, bracing, and tie beam, and had continually efforts to receive the roof style of west. The king and queen post roof truss are respectively classified with 3 types by the roof span. The king post roof trusses are composed with the principal rafter, tie beam, strut, braces, purlins, and so on. They are spanning up to about 4.5-8m, 9-12m, 12.5-16.2m, each of them has 6, 4, 2 struts and lattice members But there are practically no 6 struts and lattice members in the king post roof truss of wooden architectural properties. The queen post roof trusses enable the construction of the very large span than the king post roof trusses, the knee brace are used when bay is more than 5m between the queen posts. An further innovation was the use of iron tie bars in lieu of timber for tensile lattice members in the trusses. |
