Dynamic characteristics of tall building structures with double negative stiffness damped outriggers (2NSDO) are parametrically studied using the theoretical formula. Compared with one negative stiffness damped outrigger (1NSDO), 2NSDO can achieve a similar maximal modal damping ratio with a smaller negative stiffness ratio. Besides, the 2NSDO can improve the maximum achievable damping ratio to about 30% with less consumption of an outrigger damping coefficient compared with the double conventional damped outriggers (2CDO). Besides, the responses of structures with 2NSDO under fluctuating wind load are investigated by time-history analysis. Numerical results show that the 2NSDO is effective in reducing structural acceleration under fluctuating wind load, being more efficient than 1NSDO.

대부분의 구조물들은 강한 지진을 받을 경우, 비선형 거동의 변형이 예상된다. 구조물의 내진평가는 구조물에 가해진 지진력에 대한 변위요구와 같은 구조물의 성능평가를 필요로 한다. 여러 가지 비선형해석법 가운데 구조물의 내진역량을 계산하기 위한 가장 정확한 방법은 비선형 시각이력해석(NRHA)이긴 하나 많은 시간과 노력이 요구되고 있다. 따라서 구조물의 비선형 거동을 보다 간편하게 예측하기 위한 정확하고 실용적인 비선형 약산해석법에 관한 연구들이 활발히 진행되고 있다. 일부 약산적 방법 중 능력스펙트럼법(CSM)은 개념적으로는 간단하나 반복적인 계산과정과 함께 때로는 해가 없거나 중복적인 해를 갖는 약점을 갖고 있다. 본 연구에서는 강성골격곡선으로부터 산정한 구조물의 초기 탄성진동주기 T와 응답스펙트럼으로부터 산정한 비선형 유사가속도 h$_{y}$ /g 및 연성비 $\mu$를 사용하여, 반복적인 계산과정 없이 복합구조물의 내진성능을 평가하는 비선형 직접스펙트럼법(NDSM)을 고려한다. 다양한 지진과 복합구조물에 대한 NDSM의 신뢰성과 실용성을 비선형 시각이력해석(NRHA) 결과와 비교함으로써 검토하였다.

The purpose of this study is to bring light on the characteristics of the transition in the Ddeulzip. The subject of this study is clan village of Pungsan Kim's family in Andong Cultural Area. Architectural transition of Ddeulzip is analyzed into three part. The first part is settlement of family. In this process, there is a background and many types of settlement. The second part is the extension of family. The extensional types are 'near-by branch' and 'far-away branch'. The last part is variation of housing. Spacial requests of residence are changed endlessly. Thus the spacial types of Ddeulzip are changed by the construction time of building. In many case, we couldn't decide the building period. The genealogy of Chosun Dynasty is the base of family history. In this study, the construction activity of Ddeulzip is based on the genealogy. The phylogenetic tree of Ddeulzip in clan village is constructed by the genealogy. The figures of the type of bunch of grapes is made by phylogenetic tree based on the genealogy. Omi Village in Andong was settled at first in the 15C. The cause of settlement is the aim of escape from political oppression. For long time, Omi Village is developed gradually. There area is divided in some small family boundary. There spacial types are contained the characteristics of many times. Orock Village in Bonghwa is settled for search of best environment in the last of 17C. At that time, a lot of families of same clan are gathered in that village. For short time, Orock Village is enlarged quickly. Thus there spacial type is similar each other. But boundary of entire space of outdoor is constructed clearly by pavilion area, housing area and sanctuary area.

This study is one that estimates the architectural composition as well as the location of guest house of Haemi Eupseong on the basis of the analysis of modern and contemporary data related to Haemi Eupseong. It is significant that this study has presented an opinion that can become a practical basis for the historical research of the prototype of Haemi Eupseong of the late Chosun Dynasty through the analysis of modern and contemporary data that had been unsatisfactory among the fruition of studies conducted in relation to Haemi Eupseong. The outcomes achieved by this study are as follows. Firstly, it was verified that the guest house of Haemi Eupseong that has been restored is one that has different architectural composition than the prototype of the late Chosun Dynasty and is restored in a different location. Secondly, in respect of architectural composition of guest house found by the analysis of the picture, it was confirmed that the government office has one step higher than the double-wing house in the form of the roof. Thirdly, the location of the guest house of Haemi Eupseong of the late Chosun Dynasty is judged to be the periphery area where the current restored guest house is located, which is where the teachers' building of Haemi elementary school was located. Fourthly, the prospect of the guest house of Haemi Eupseong is decided to be similar direction to the current restored guest house with the greatest possibility of having the same direction with the arrangement of teachers' building of Haemi Eupseong elementary school.

건축구조물의 응답스펙트럼 해석법은 주로 내진설계를 위하여 많이 사용되고 있고 시간이력 해석법은 기계, 설비, 사람에 의한 하중 등이 건축물에 가해지는 경우에 많이 사용되고 있다. 응답스펙트럼 해석법과 시간이력해석법을 비교해 보면 시간이력 해석법은 복잡하고 분석이 어려우며 해석에 시간을 많이 필요로 하고 구조물이 복잡해질 경우에는 해석이 어려운 경우도 있다. 본 연구에서는 응답스펙트럼해석법을 이용하여 기계나 사람에 의한 하중을 받는 건축물 바닥판의 연직응답을 구하고자 한다. 이를 위하여 모드조합에서는 CQC기법을 적용하였으며, 사람의 활동을 중심으로 하중간의 상관관계를 분석하여 해석에 적용하였다. 제안방법은 시간이력해석결과와도 비교하였으며 하중간의 상관계수는 복수의 하중을 받는 바닥판구조물의 응답스펙트럼 해석에 반드시 고려해야 하는 결과를 얻었다.

Architectural embodiment of a national identity has long been a significant topic in Korean architectural circles. For this reason, it must be helpful to examine the so-called, 'National Romanticism' of Finnish architecture around 1900 in that Finnish architects of the time struggled to embody their national identity through their projects. Considering the historical and linguistic affinities between Finland and Korea, the Finnish architectural situation draws . our additional attention. This paper aims at showing its historical background, the meaning of each type of buildings in the stream, and limitations it implies. The atmosphere of Finnish nationalist movement, which was provoked by [Kalevala] publications (1835; 1845) and shown in Karelianism, was heightened by Tsarist Empire's Russification programme of Finland in the late 19th century Architecture was one of the most important genres expressing her national identity. Finnish national romantic architecture could be divided into three. The first is a log house style for artists' studio house, motivated by the Finnish vernacular farmstead - especially by Karelian farmhouse. This type of building signifies the Finns' will to return to their motherly soil. The second is a stone architecture style for public buildings, inspired by Finnish church or castle of an early medieval time. By using roughly-cut granite as the main exterior material, buildings of this type symbolise the toughness of legendary heroes and Finns' desire for national Independence. The third type of building was based on both of the former or more dependent on architects' Imagination and creativity. However, Finnish national romantic architecture has been criticised by some critics owing to its decorative, eclectic and self-indulgent characteristics. Probably, it was not really national but rather inter-national because of the Influences of English Arts and Crafts Movement, the American Richardsonian architecture and the continental Art Nouveau. And the negative images of 'national' and 'romantic' made some historians coin other terms like 'national realism' or 'material realism'. As another limitation, one raises the low degree of its contribution to the entire architectural history. Despite these criticisms, however, this paper argues that Finnish national romantic architecture is meaningful in itself, particularly because it illustrates vividly Finns' struggle to search for their national identity and, after all, their craving for national independence.

This study includes a review of the relevant literature and data on the Gyeolseong Eupseong, a coastal castle town of the Joseon Period. During the process of building the Gyeolseong Eupseong, Eupchi(administrative office) was transferred to several different locations for the following reasons:. first, to strengthen defensive capabilities by utilizing the locational advantages of the Seokdang Mountain Fortress, second, to secure sufficient space for holding the castle and have access to water in times of emergencies, third, to strengthen coastal defence by utilizing geographical advantages. Most of the Gyeolseong Eupseong was damaged during the Japanese colonial period. At present, there remain only part of the castle's facilities and some facilities that were restored later in modern times; 4 building sites have been identified. Remaining and destructed buildings can be identified through old maps(the local maps of 1872) and Zirizi and Eupzi(geography books). Also identified were 2 castle gate sites where a 1,500m-long stone castle wall and an ongseong(a crescent-shaped defensive structure), 5 chiseongs, and a most were constructed. The Gyeolseong area is assumed to have been a strategic foothold to defend the west coast from the days before the Three Kingdom Period. However it is very difficult to find any records created before the Joseon Period. Therefore, the time of the restoration of the Eupchi should be determined based on records created in the late Joseon Period. Finally, excavation work needs to be done to identify the locations of the castle's facilities.
