Although Changgyeong-gung was devastgated by Japanease invasion in 1592, it was restored during the reign of Gwanghaegun, had remembered of early Joseon danasty's architecturural order. It was destroyed several times by fire after that but was rebuilt immedieately. There are Donggol-do and Donggol-dohyeong, so we can fine the change of architectures in Changgyeong-gung. Jibbokheon(集福軒) and Yeongchunheon(迎春軒) are marked in another location and architectures in Donggon-do and Donggon-dohyeong. The reason has been known that it was rebuilt after the fire in 1830. As a result of reviewing the record of birth of crown prince Sado and movement of coffin of King Jeong-jo in funeral ceremony, it was confirmed that notation of Jibbokheon and Yeongchunhyeon was misprinted. In particular, Yeongchunheon confirmed the possibility that the existing building was built by extending it while applying the asymmetrical building with four-purlins structure method during the reign of King Jeongjo, and that it was reconstructed by moving Yeonyeonghap when it was destroyed by fire 1830. And although now Jibbokheon and Yeongchunhyeon(延英閤) are connected, nothern part of Jibbokheon did not burn in the fire, so it was judged that original architectural plan were maintained until now. The current building north of Jibbokheon was built before 1695 (21st year of King Sukjong), which was first identified in the Gunggeolji(宮闕志), and there is a possibility that it may have been a part of Janggyeongmun(長慶門) inner corridor built before 1633. The present building north of Jibbokheon has great architectural significance in that it maintains the structural method of the early Joseon Dynasty which was often applied to buildings with a small scale of inner palace.

본 연구는 한중 고건축 내부 가구(架構) 중 소슬재의 위치와 도리와 보의 결합 형태를 분석하여 동아시아 목조구조 체계 원리를 이해하기 위한 기초적인 연구이다. 동아시아 국가인 한국과 중국의 고대 목조건축은 서까래와 도리, 그리고 보를 결합하여 건물의 윗부분을 구성하고 기둥과 결합하여 건물의 기본 골격을 형성하는 구조를 가지고 있어 목조 구조 체계의 원리가 크게 다르지 않다. 다만, 세부적인 기법상의 차이가 지역성과 시대성, 국가성을 띠고 있다. 중국건축 내부 가구 중 도리와 보의 결합 형태와 차수(叉手), 탁각(托脚)의 지지점 위치가 시대에 따라 차이점을 보이고, 역사적으로 다양한 왕조에 따라 세부 수법이 다른 것으로 보인다. 15세기 이후 건축에서는 차수와 탁각이 없어지는 현상을 보이며 특히, 탁각은 명대 관식건축에서는 완전히 없어졌으며 주된 이유는 도리와 보의 결합 방식의 차이가 크게 작용한 것으로 볼 수 있다. 15세기 이전에는 도리와 보가 서로 떨어져 결합되고 있었으나, 15세기 이후는 도리와 보가 서로 결합하고 보의 단면적이 비약적으로 커져 도리 좌굴을 방지하는 수법이 발달한 것으로 보인다. 탁각의 경우 당 오대 시기에는 탁각의 상부 위치를 봤을 때 도리와 직접적인 결합은 없으며, 도리의 좌굴을 방지하는 부재보다 내부 가구의 안전성을 유지하는 부재라고 볼 수 있다. 송대 이후 원대까지도 송 "영조법식"의 기록과 다른 건축물이 많은 것으로 보아 탁각의 적용 여부는 지역, 혹은 장인의 수법에 따라 다양하게 나타난 것으로 보인다. 원대 이전 우진각 지붕의 측면 도리 부근과 팔작 지붕 합각 아래 구조에서도 탁각이 있는 것 보아 종단면과 횡단면에서 모두 볼 수 있는 부재이며, 지지점의 위치를 보아 도리를 직접 지지하는 부재라기 보다 우진각 지붕의 측면 구조나 팔작 지붕의 측면 합각 구조의 안전성에 기여하는 부재로 보인다. 한국건축 중 고려시대에 반 'ㅅ'자형 소슬재(중국명: 탁각[托脚])가 유행하지 않은 이유는 도리의 좌굴을 방지하는 기법(도리 받침재)이 널리 유행하여 반 'ㅅ'자형 소슬재를 사용하지 않아도 도리가 안정적으로 유지하는 방법을 선호한 것으로 볼 수 있다. 이 시기의 도리는 도리+장혀+도리 받침재+보의 구성을 보여 도리가 직접 보와 결구되지 않는 특징이 있으며, 조선시대 이후 도리가 보의 단면적의 범위에 속해 도리가 좌굴 되는 현상을 방지한 것으로 보인다. 이는 15세기 이후 중국건축에서도 같은 모습을 보이며, 15세기 이후 도리 좌굴에 대한 세부 기법이 한중 양국의 지역성과 국가성을 뛰어 넘어 보편성을 가진 예라 생각된다. 조선중 후기 건축에서 지붕부의 하중을 줄여 주는 방법인 덧걸이 수법이나 덧서까래 사용은 도리에서 보로 전달되는 하중을 줄여주어 도리 좌굴을 감소시켜 주는 효과가 있으며, 이는 조선시대에 건물을 영조하는 장인들의 도리 좌굴을 방지하는 또 다른 기술이라 할 수 있다. 한중 고건축 도리와 보의 결합 구조와 소슬재의 연구는 고려시대 이전 건축을 복원, 설계하는 연구에 기초적인 연구를 제공할 수 있을 것으로 보인다.

Hoein Hyanggyo is a confucian shrine at Hoein, Boeungun, Chungbuk, Korea. Using tree rings, we dated its lecture hall, Myengryundang which is a two-storied wooden structure with half-gabled and half-hipped roof. The woods of Myengryundang consisted mainly of lard pine (probably, Pinus densiflora). We collected 27 samples (4 columns, 2 beams, 5 purlins, 4 capitals, 8 floor frames/boards and 4 others). The results indicated that the major cutting year was A.D. 1702. This date helped to correct the miswritten Chinese-calender date which was recorded in the document for the framework-raising ceremony.

This thesis mainly deals with how 'count of Ryang' was used in Joseon dynasty. Count of Ryang means how many purlins were used in the building with longitudinal section. As a result, the notion of Ryang in Joseon dynasty does not differ from now one. But the usages of that are slightly different to the present day. In Joseon dynasty, count of Ryang mainly was appeared with another word, count of Kan. Count of Kan has two meanings. One is the length, and the other is the area of building. When they used the count of Ryang combined with Kan, count of Kan had the meaning of length. By doing that, count of Ryang indicates the size of flank, count of Kan indicates the length of front. In the 19th century, count of Ryang looks similar to the past, but count of Kan shows another aspect. It did not indicate the length but the area of building. Through this study, although the usages of Ryang were different to the present, the concepts of Ryang were similar in Joseon dynasty.

This thesis mainly deals with how 'count of Ryang' was used in the Daehan Empire. Count of Ryang means how many purlins were used in the building with longitudinal section. As a result, the notion of Ryang in the Daehan Empire does not differ from now one. But the usages of that are different from the Joseon Dynasty, and from the present. In the Daehan Empire, count of Ryang mainly was appeared with another word, count of Kan. In the Joseon Dynasty, they used the count of Ryang combined with Kan. Count of Kan had the meaning of purlin-directional length. By doing that, count of Ryang indicates the size of flank, count of Kan indicates the length of front. But in the Daehan Empire, count of Kan, especially the beam-directional length was considered at first, and then count of Ryang. Separately they used another count of Kan meaning the area of building. By using the combined words, count of Kan and Ryang in the beam direction, they got focused on the frame of wooden structure than before.

The roof improvement project is being carried out under the government's leadership for the sake of national welfare. The project is to replace the asbestos slate roof with a metallic one. In this study, the structural safety of the improved roof was examined and the project guidelines were reviewed. The causes of the roof damage were investigated and the structural analysis was performed for the roof frame subject to wind and snow loads. Metallic roof assemblies have higher strength and load resistance capability than usual slate ones, so the structural safety is governed by the frame. The stresses of the roof frame elements caused by the wind and snow loads were analyzed according to roof frame with various spacings between the rafters and the purlins. Wind load analysis was performed by 24, 28, and 38 m/sec of the basic wind speed. Snow load analysis was carried out by 0.5, 1.0 and $2.0kN/m^2$ of the ground snow load. As the analysis result, the current spacing and the size of the lumber did not satisfy the Korean building code specification. To secure the safety of the roof improvement project, the spacing of the roof frame elements and the size of the lumber should be determined based on the analysis results by structural engineers.

영광 불갑사의 대웅전에 쓰인 목재의 수종을 식별하기 위하여 기둥, 보, 평방, 창방, 도리, 사래, 추녀, 서까래 등 총 88점을 조사하였다. 수종은 경송류(소나무류), 전나무속, 참나무(상수리나무류), 느티나무 등 4수종이 식별되었다. 기둥과 사래는 느티나무의 비율이 높았으나, 다른 부재는 경송류가 대부분이었다. 기둥과 사래의 느티나무의 비율이 높은 것은 조선후기 이전에는 소나무보다 재질이 우수한 느티나무가 많이 사용되었기 때문이라고 생각된다.

This paper presents the dynamic characteristics analysis of the purlin-sheet roofs by the random vibration theories. Results show that the natural vibration frequency of the purlin-sheet roof is low, while the frequencies and mode distributions are very intensive. The random vibration theory should be used for the dynamic characteristics of the roof structures due to complex vibration response. Among the first 20th vibration modes, the first vibration mode is mainly the deformations of purlins, while the rest modes are the overall deformations of the roof. In the following 30th modes, it mainly performs unilateral local deformations of the roof. The frequency distribution of the first 20th modes varies significantly while those of the following 30th modes are relatively sensitive. For different parts, the contributions of vibration modes on the vibration response are different. For the part far from the roof ridge, only considering the first 5th modes can reflect the wind-induced vibration response. For the part near the ridge, at least the first 12 modes should be considered, due to complex vibration response. The wind vibration coefficients of the upwind side are slightly higher than that of the leeward side. Finally, the corresponding wind vibration coefficient for the purlin-sheet roof is proposed.

A modification of the TEACH-like computer program based on the k-$\varepsilon$ turbulence transport was applied for predicting air mixing patterns and temperature distributions in a rectangular, slot-ventilated enclosure having obstructions ; a rectangular obstacle with heat flux, solid walls separates the passage and the pig pens, and purlins beneath the ceiling. Air flow patterns were calculated for the cases with and without the purlin, extending 300mm beneath the ceiling. Comparisons of prediction data of Randall & Battams(1976) showed air flow pattern predicted well for the case without the purlin. Heat was accumulated at the corner of the left side of the solid wall and the right-upper region of the simulated pigs. However the air distribution pattern was completely different from data for the case with the purlin. The deviation from the observation may be attributed to the difference of the geometric configuation. Exploring the cause of the deviation should be conducted in a further study. Temperature stratification was also observed due to incomplete mixing. The obstruction in the route of the inlet air jet at inlet should be avoided since most of kinetic energy dissipates at the abstacle duet to impingement.

In this study, we evaluated the applicability of proper embedded depth of fillings by examining the uplift resistance using spiral foundation and top base foundation. As a result of the model test, the maximum uplift resistance increased with the embedded depth. The maximum uplift resistance of each region was found to be 50cm depth. The spiral foundation was 335.14N of Sancheong, 312.32N of Seongju, 403.94N of Wanju, and the top base foundation was 745.06N of Sancheong, 1028.82N of Seongju and 950.76N of Wanju. The yield point after the elastic section in the stress-displacement graph of the top base foundation was calculated as the maximum uplift resistance. For this reason, farmers do not actually use top bases foundation. Therefore, it was considered that the additional load increase due to slip connector will not occur. Model test results show that the maximum uplift resistance increases with the purlinss installed under the ground. Therefore, additional comparative studies through purlins installation will be needed.
