A dapo type bracket system which consists of chuganpo(柱間包) and chusangpo(柱上包) with a fake-beam adopted a nemok-dori member to cope with oemok-dori member in order to obtain balance between the outer-side and the inner-side of the bracket system. The middle part of the longest rater in the dapo system is supported by three points made by oemok-dori, jusim-dori and nemok-dori members and the area between the rafer supporting points forms a supporting area. The increase of rafter supporting points and supporting area leads to heightening the structural stability and the efficiency of load delivery. In the eave of dapo system the portion where the three supporting points formed by oemok-dori, jusim-dori and nemok-dori members shows as 33% in the early period, 71% in the middle period and 78% in the later period. On the contrary the portion where more than one of the three dori members were omitted shows as 67% in the early period, 29% in the middle period and 22% in the later period. This is the result of the increase of the number and the distance of steps in the dapo bracket system as time goes on. This is because the structural role of three supporting points becomes important as the increase of distance between the dori members leads to the increase of load which burdens on each dori member.

The purpose of this study is to examine the species of wooden members used in the Youngsanjeon Hall of the Sucknamsa temple in Anseong, Korea. Ninety-five wood samples from pillars, head-penetrating ties, beams, corner rafter, rafter, floor board and other wood members were identified. Seven species identified were hard pine, exotic pine, Zelkova serrata, Ginkgo biloba, Diospyros, Quercus(Cerrus) and Pyrus spp. In the case of pillars, eight were hard pines and the others Zelkova and Pyrus. Species of angle rafter were Ginkgo biloba and Zelkova. and those of beams were one hard pine and one Zelkova. Two purlin samples were Quercus(Cerrus) and rafters were hard pines except one Ginkgo and one exotic pine. Roof-filling timbers were identified as Zelkova and Diospyros spp. The other samples of roof-filling timbers were all identified as hard pines. The use of Ginkgo and several hardwoods in addition to hard pines may indicate supply of local logs near the Sucknamsa temple.
