The traditional earth wall structure consists of a Joongkit(a small reinforcing post inside a wall) and a Oe(a miscellaneous tree, rendered laths) based on the space between the columns and applying the soil. The members who act as the base layer before applying soil used joongkit, sakmok, and oemok, which are known to correspond to the current joongkit, gasisae, and lath strips. This study was designed to understand the following through an analysis of the ancient texts, such as uigwe. Through a study on the usage and specifications of joongkit recorded on the uigwe, I wanted to reveal that joongkit is a material that has different specifications, functions, and installation techniques from current joongkit. The purpose of this study was to present the differences and technical features of the components of use for two types of oeyeokki technique of traditional wall. In addition, the items to be considered at the actual cultural heritage repair site were reviewed in the restoration of the earth wall weaving technique.

Several water tanks installed in the building were damaged during the Gyeongju earthquake (2016) and the Pohang earthquake (2017). Since a water tank for fire protection is very important component, seismic safety should be ensured. In this study, an interaction between a water tank and a building was studied by the dynamic analysis of the RC building with the water tank. In case the water tank was installed on the roof of the RC building, it was confirmed that it did not significantly affect the response of the building. Based on the result, dynamic response characteristics of the water tank in the building were studied using two SDOF models represented dynamic behavior of the water tanks under earthquake. An earthquake time-history analysis was carried out with variables of aspect ratio of the tank, story of the building, and installed location in the building using three kinds of earthquakes.

최근 필로티는 공간의 활용도나 미관상의 이유로 많이 사용되고 있다. 필로티는 외벽보다는 안쪽에 위치하나 외기에 접하는 형태로 강한 바람이 불 때, 바람길이 형성되고 강한 압력을 받아 필로티의 천장 및 벽면 부분의 외장재가 탈락하는 피해가 발생한다. 현재 건축구조기준(KBC-2016)에서는 필로티 건축물에 대한 천장 및 벽면의 풍압계수가 제시되어있지 않아 필로티 부분의 주골조 및 외장재에 대한 구조설계에 어려움이 있다. 이에 본 논문에서는 저층구조물의 관통형 필로티에 대한 풍압실험을 진행하여 풍압계수를 산출하였다. 실험 모형의 변수는 필로티의 높이와 폭으로 두었으며 변수에 따라 풍압계수를 산정하고 풍압분포의 변화를 비교·분석하 였다. 따라서, 필로티의 여러 변수 중 가장 불리한 풍압계수를 제시하여 이를 주골조와 외장재 설계 시 기초자료로 제공하고자 한다.

본 연구는 건축설계 계약에서 이루어지는 구체적인 불공정계약의 관행을 수집하고, 계약서에 드러난 ‘갑’의 절대적 우위를 교정하기 위해 시작되었다. 이를 위해 2009년에 국토부고시로 발표되어 현재 그대로인, 업계에서는 거의 무용지물이나 마찬가지인 ‘건축물의 설계 표준계약서’를 대신해 새로 표준계약서 제정을 제안했다. 또한 표준계약서의 사용을 제도적으로 뒷받침하기 위해 관련법 즉, 건축서비스산업 진흥법, 건축법, 건축사법, 국가계약법, 그리고 ‘공공발주사업에 대한 건축사의 업무범위와 대가기준’ 역시 개정되어야 하고 이를 제안했다. 건축물의 최종 소비자는 불특정 다수인 국민이다. 그러나 건축물의 설계계약서는 사인간의 계약이라며 사적자치의 자유만이 작동되고 있다. 국민의 안전을 담보하는 건축물을 위해서는 이제라도 계약공정의 원칙이 작용하도록 일정 부분 국가가 개입 되어야만 한다. 이러한 법, 제도의 개정이 상호 유기적으로 이루어지고 시스템이 작동되어야 건축물이 건강하고 아름답게 세워질 것이다.

A major performance stage carpenter, Jang Insang led performance stages from the 1719 Sukjong Royal Banquet and was confirmed by historical records to be the first craftsman. Lee Wandeuk led the Hwaseong Fortress performance stages of the Jeongjo period and Gichuk Jinchan performance stages of the Sunjo period. The carpenter techniques he used during the Jeongjo period were succeeded to the Sunjo period. Ahn Sungil was the head craftsman who led the performance stages of Jagyeongjeon Jinjak, Muja Jinjak, and Gichuk Jinchan of the Sujo period, under which the foundation for court palace performances was laid. The progression of major carpenters includes Jang Insang of the Sukjong period, Jeon Yoochu of the Yeongjo period, Ahn Sugil of the Sunjo period, Yoon Seoksin of the Heonjong period, Kim Yoonsik of the Gojong period, Lee Jongyoon, Kim Soongil, Seo Sangmook, and Han Sujoon. In addition, the Major Repair of Injeongjeon Hall (1857) of the Cheoljong period was the most important palace construction project for transferring the carpenters’skills. Through this project, Ahn Sungil of the Sunjo period, Kim Myeonggap, Yoon Seoksin of the Heonjong period, Kwon Deuknyang, and Kim Sungil of the Gojong period were able to interact with each other. That is, this major repair project of Injeongjeon Hall reflected the major carpenters’best techniques through performance stage construction, showing the progression of Ahn Sungil, Yoon Seokshin, and Kim Sungil, who led the constructions of Gichuk Jinchan of the Sunjo period (1829), Mushin Jinchan of the Heonjong period (1848), and Jeonghae Jinchan of the Gojong period (1887), the most impressive performance stages of the late Joseon period. The carpenters of the court performance stages participated in important construction projects of the royal palace, reflecting the superior technical skills of the carpenters in the construction of court palace performance stages. The carpenters who played a leading role in the construction of performance stages were able to interact with one another and transfer their excellent technical skills, providing the driving force that allowed court performance stages to blossom into splendid and high-quality court stages in the late Joseon Dynasty.

Modern Joseon Architecture is North Korea's unique building style that interprets Korean traditional architecture in a modern way, and its most distinctive design feature is the Paljak roof that decorates the upper part of the buildings. This paper argues that continuous attempts at characterizing the nature of traditional Korean architecture in the late 1950s and early 1960s developed the theoretical rationale for the exclusive use of the Paljak roof in Modern Joseon Architecture. It also argues that the construction of the Pyongyang Grand Theater and the Okryu Restaurant during this period became a decisive moment for the formalization of the Paljak roof. The double roof rafters and gables and the "cheerful yet solemn" roofline were considered as main characteristic features of the Korean roof and the Paljak roof perfectly fits this description. Particularly, in North Korean society where Kim Il Sung became idolized as an impersonalized deity, an anecdote in which Kim Il Sung fixed a prominent gabled roof in the Pyongyang Grand Theater into a Paljak roof has allowed for the roof to gain an exclusive status. Hence, almost all Modern Joseon Architecture since the 1960s accepted the Paljak roof’s monopoly position, rather than experimenting with other traditional roof types.

Seongjeonggak Hall in Changdeokgung Palace, although built after the Japanese Invasion in 1592, displays the architectural style and structure of Early Joseon period. It did not include ondol (Korean floor heating system) and contained Early Joseon style window frames. Later, King Jeongjo installed ondol as he repaired the building into a more convenient office. The initial construction of Seongjeonggak Hall was based on the architectural ideology of the Early Joseon Period, which divided up the space according to the season. Thus, the initial structure of the building consisted of a joint of a one-story building and a two-story building with the top floor of the latter specialized for hot and humid season. The two-story building was called ‘chimnu(寢樓)’, and its top floor was called ‘nu-chimsil(樓寢室)’

우리나라의 바람은 계절풍, 태풍, 저기압 전선풍으로 나눌 수 있다. 또한 우리나라는 산지가 많고 삼면이 바다로 둘러싸인 지 리적인 특성도 갖고 있다. 이로 인해 각 지역의 풍향마다 풍속이 균일하게 불어오지 않는다. 내풍설계 시 사용하는 풍속은 건축구조기 준에 규정된 100년 재현기대풍속을 전풍향에 대해 동일하게 사용한다. 이 값은 풍향을 고려하지 않기 때문에 다소 보수적인 설계가 될 수 있다. 이 연구에서는 10개 지역을 대상으로 16풍향에 대한 분풍속을 수집하여 풍향별 100년 재현기대풍속을 산출하였다. 기상청에 서 수집한 자료를 균질하게 하기 위해 풍향별로 유효높이를 고려하였고, 지표면조도구분을 하는 방법으로 가스트계수방법과 목측방법을 사용하였다. 풍향별 100년 재현기대풍속을 산정하기 위한 확률분포는 Gumbel분포를 사용하였고, 경험적 초과확률로는 Hazen방법 을 이용하였으며, Gumbel분포와 Hazen방법의 적합성은 적합성평가함수에 의해 판단하였다. 이것을 토대로 각 지역의 풍향계수를 산출하였고, 풍향계수의 비교를 통해 지역별, 풍향별 풍속의 특성을 파악하였다.

KBC-2016에서는 건축물 구조안전성 검토를 위한 100년 재현기대풍속은 지역별로 명시하고 있다. 하지만 사용성 평가를 위 한 재현기대풍속은 지역별로 명확히 제시하고 있지 않다. 보다 합리적인 사용성 평가를 위해서는 1년 재현기대풍속을 규정할 필요가 있다. 또한 한반도의 지리적 특성상 풍속은 풍향과 지역의 영향을 강하게 받기 때문에 풍향을 고려할 필요가 있다. 이 연구는 최근 10 년간의 일최대풍속을 이용하여 75개 지역 풍향별 1년 재현기대풍속 및 풍향계수를 추정하였다. 일최대풍속의 확률분포는 Weibull분포 를 사용하였다. 최종적으로, 이 연구의 풍향별 1년 재현기대풍속과 선행연구결과를 비교하여 한반도의 풍향별 풍속의 변화 경향도 파 악하였다.

The damage detection method using the extended Kalman filter(EKF) technique has been continuously used since EKF can estimation the responses of the damaged building structure and the stiffness of the structure. However, in the use of EKF, the requirement of setting the initial paramters P, Q, and R has caused the divergence and instability of the state vector, and various researches have been conducted to determine theses parameters. In this paper, adaptive extended Kalman filter(AEKF) method is proposed to solve the problem of setting the values of P, Q, and R, which are important parameters determining the convergence performance of the EKF state vector. By using the AEKF method proposed in this study, the P, Q, and R parameters are updated every k steps. The proposed algorithm is applied for the estimation of stiffness and the damage detection of 3-DOF problem. Based of the verification, it can be found that the selection process for the values of P, Q, and R can improve the convergence performance of EKF.

우리나라에서는 1995년 부터 시설물의 안전관리에 관한 특별법(이하 시특법)이 시행되어 왔다. 그 이후, 우리나라에서는 크고 작은 사건사고가 있었고, 구조적 안전성 확보를 위해 수차례의 법 개정이 있었다. 한국시설안전공단에서는 건축물 정밀안전점검 및 정밀안전진단 보고서를 시특법에 근거해 평가하며 그 결과를 사례집을 통해 주기적으로 발간하고 있다. 본 연구의 목적은 안전성 검사 및 진단을 위한 기술 및 제도 개선 방안 도출에 있다. 이를 위해 2011 년부터 2015 년까지 시설안전공단에서 발행한 정밀안전점검 및 정밀안전진단 보고서의 평가 사례 데이터를 비교 분석하였다. 비교 분석 결과를 토대로 정밀안전점검 및 정밀안전진단 수행 중 발생하는 문제의 원인을 파악하기 위해 전문가를 대상으로 한 설문 조사를 실시하였다.

For the proper preservation and utilisation of Regional Modern Heritage Buildings, it is necessary to study the history of local modern architecture based on a broad understanding of the region and also to architectural history. The aim of this study is expand the awareness and multi-faceted interpretation of modern architecture in Kwangju in the 1940’s to 1950’s, by exploring the origin of regional modern architecture from new perspectives. As a part of the discussions of the perspectives, this study will be therefore explained with the regional correlations between the architect Kim Han-seop’s works and activity, influential politicians, strong enthusiasm of education, architectural characteristics of the main building of Chosun University, architecture schools and association in Kwangju. Then, it will be finalised that Kim Han-seop and the main building of Chosun University are directly and indirectly correlated and affected each other strongly.

This paper is to clarify on the characteristics of the Haeeumwonji and the Main Palace of the Goryo Dynasty. The architectural techniques and construction methods such as embankment, stylobate, stairway, foundation stone, and pave are similar to those of the Haeeumwonji and the Main Palace of the Goryo Dynasty. In order to express the hierarchy of the area and building, the materials, techniques, and forms of the embankment, stylobate, stairway, foundation stone and pave were used differently. The paving of the floor of the main building and area is also an active expression of the hierarchy and status of the building area and the building through the use of building materials, techniques and forms. This result confirms the support of Goryeo royal family and the upper class for the construction of Haeeumwonji, which is recorded in the historical documents. And it also shows that the architectural techniques and processing method of the same period were shared in the capital and provinces, which is an important clue that proves that the capital-centered architectural technology has spread to the provinces. It is expected that additional research will be needed on the characteristics of the period of 12th century architecture technique in which Haeeumwonji was built.
