본 연구는 단조가력 하중을 받는 실물크기 비닐온실의 기둥-서까래-도리 접합부의 역학적거동을 알아보기 위해 현장에서 시공되고 있는 두 가지 형식의 실험체로 구조실험을 수행하였다. 실험결과를 바탕으로 두 가지 형식의 접합부에 대해서 휨성능을 분석하고 접합부 분류를 시도하였다. Type B 는 Type A에 비해 휨 성능이 77% 수준으로 나타났으며 두 형식 모두 강성 및 휨내력이 강접합 수준에 미치지 못하는 것으로 나타났다. 기둥-서까래-도리 접합부의 거동은 용접부 및 체 결구 변형에 의한 국부좌굴이 지배적이었다. AISC 기준에 의한 접합부 분류 결과, Type A와 B 접합부 모두 설계 시 가정하는 강접합 성능에 미치지 못하는 결과를 보였으며 단순 접합으로 분류되는 것으로 나타났다. 따라서 접합부 성능평가 및 분류 결과, 접합부 성능을 고려한 온실 설계가 이루어져야 하며 신뢰성 높은 온실 구조설계를 위해서 온실 접합부에 대한 명확한 설계기준 정립 연구가 필요할 것으로 판단된다.

In this study, I would like to inquire about the composition of oegi(外機) on the hip and gable roof. Oegi purlin compose the basic member of framework of a hip and gable roof in both sides roof, supporting the inside end of the side rafter. However, the oegi purlin is not simply used to form hip and gable roof. The effects of using oegi purlin have the advantages of spatial. The spatial advantages are the width of the toekan(退間) increases as the oegi purlin escapes from column row and to increase the ceiling height by becoming a point of staying the ceiling. That reflect the desire to expand indoor space due to changes in worship behavior. Oegi purlin was used not only for structural needs, but also for altering in indoor space due to the changing times.

As a part of the research on existing structures of private homes from Joseon Era. Focusing on one hundred twenty five-purlin houses, the current study investigated the features and characteristics of the house structure from style, size, proportion and roof pitch, and measurements of key parts, and developed the following conclusions. Most are single-houses (89, 83%), and among them, there are 47 single front-terrace houses (39%), which is the highest number. The sizes of lower house structure do not differ greatly depending on the vertical structure, and single rear terrace house and double-house have relatively larger side sizes. The size of upper structure is larger in double-houses compared to other vertical structures, indicating a relatively higher roof. The cross-section measurement of major parts show that double-houses are larger than single-houses by 3cm in pillar, 3-4.5cm in crossbeam length, and 4.5cm in crossbeam width. However, Janghyeo width was consistent at 7.5 to 10.5cm, maintaining uniformity regardless of vertical structure of the houses. In addition, the cross-section measurements decreased from sixteenth to nineteenth century, with the size of pillar size decreasing the most. The result that the Janghyeo width is not related to the house structure house confirmed that the Janghyeo width was kept consistent regardless of the size of the house structure.

This study is to present Chinese character notation for common use through investigation of examples and graphonomy related literature with beam and purlin of wooden members and its conclusions are as follows. It suggests two commonly used Chinese characters of beam and purlin. The first method of indicating them is Riyang(樑) for beam and Hang(桁) for purlin and the second method is Bo(保) for beam and Hang(桁) for purlin. Riyang(樑) as the first method was already used in the Joseon period and was profitable to convey limited meaning as wooden term compared to Riyang(樑) with wider meaning and Bo(保) as the second method contained logical association and hieroglyphic connection of Bo(保) as the Korean character. Hang(桁) for purl in was presented by both the first and second methods and it was already used in the Koryeo age, also commonly used as the term of purlin in China and Japan and it was also presented as letter containing logical and hieroglyphic connection with Hyeng(行).

This study examines on the structural Methods between purlin and beam at Wooden Architecture in Joseon Dynasty(1372~1910). Through the investigation, it is verified that the structural methods between purlin and beam is the technique utilizing tenon joint(통장부맞춤), Sungeoteok joint(숭어턱맞춤), dovetailed tenon joint(주먹장맞춤). And the methods of tenon joint is followed by the Sungeoteok joint, which is used in the buildings after middle Joseon dynasty. The method of tenon joint(통장부맞춤) is to connect the beam with the purlin by carving out the head of the beam as '一' shape. And the structural methods between Janghyeo(장혀, timber under purlin) and beam is halved joint(반턱맞춤) and tenon joint (통장부맞춤). The buildings in late Goryeo Dynasty and Joseon Dynasty adopted the method of tenon joint between purlin and beam. The method of Sungeoteok joint is to connect the beam with the purlins by carving out the head of the beams '凸' shape. And the structural methods between Janghyeo and beams is halved joint(반턱맞춤) and tenon joint(통장부맞춤), the method of tenon and step joint(통장부턱맞춤), dovetailed joint between beam and Janghyeo to increase the security of shear force.

The purpose of this study is the analysis of 'perpendicular crossing Dori' with a structural character of Ddeulzip in Andong cultural area. There are many structural methods to solve the problems of Ddeuljip which is connected space in the rectangular type. There are 'Slope Base', 'Woosangak' roof, 'Seosangak' roof, and '4 beam roof framing' Moreover, they have been used 'perpendicular crossing Dori'. Its characters are as follows ; 1. The 'perpendicular crossing Dori' structure is occurred in different depth of width and length space of 'ㄱ' typed plan. At that time the beam of width is crossed in the middle of the beam of length without the order under them. 2. The 'perpendicular crossing Dori' structure is the method of free depth of width in regular distance of column which is different from general usage of balcony order. 3. The 'perpendicular crossing Dori' structure is founded north-western area of Andong Cultural Area(Bonghwa, Andong, Youngju, and Yeacheun). The best old sample was in Andong(16C) and the next is Yeacheun(17C) and the last is Bonghwa(18C). 4. The frequency in use of roof type of 'perpendicular crossing Dori' structure is 64% of 'Seosangak' and 36% of 'Woosangak'. The sample of 'Woosangak' house of 'perpendicular crossing Dori' structure is concentrated in Bonghwa. 5. The best merit of the 'perpendicular crossing Dori' structure is usage of double swing window in front of Anbang, It is the spacial success which overcomes the structural limits. And it is the structural rationality.

In this study, we suggest the process that can effectively evaluate safety and serviceability of purlin members of new traditional Korean-style house. It is composed of three parts, that is, input, structurecalculation, and structure-evaluation part. We expect that this suggested process can help structural engineers to secure safety and serviceability of new traditional Korean-style house.
