A Study on the Development of Section Tables for Lateral Members of Hanok

한옥의 수평부재 단면조견표 개발에 관한 연구

In this study the section tables were developed which help to decide appropriate section size of lateral members of 3-ridge and 5-ridge roof hanok, such as, ridgepole, Jusim-Dori, Dori and Jangyeo, Pyung-Bang and Chang-Bang, and rafters. The main items which were considered in developing section tables are roof structure types, timber species and material properties, overburden loads, length and disposition of members. We proposed schemes for computing allocation loading area for each lateral members according to geometric shapes and topological disposition between members. The length of members and size of sections are restricted to a field applicable ranges. The filed applicability of the developed section tables were evaluated using a test-bed hanok in Myongji University and a pilot hanok in Eunpyeong hanok village. The evaluation was carried out by comparing three results of sections from detailed structural design, section tables and actual construction. It turns out that the sections from section tables are somewhat conservative but has sufficient field applicability in early design stage.
