The purpose of this study is to identify ways of remodeling from the traditional hanok to the modern local governmental facility in 1910s. Analysing architectural drawings in the National Archives of Korea, 58 hanok remodeling cases of 52 facilities were verified like the provincial office, county office, county court from 1907 to 1910s. Using hanok as the local governmental building, exterior walls were all changed to the scaled-wooden wall like one of western-wooden building in 1910s and the western-style entrance was set. Change of the plan caused by remodeling interior walls had an intention of the centralized closed plan. Remodeled semi-outer corridor using the space of the eave became changed to the inner corridor with expansion of space. Expansion of hanok for spatial demand was in three ways. First was the expansion towards the eave space, second was direct extension from hanok, and last was the use of external corridor to the new building. Using the eave space was simple but had limitation of space, it was planed with other expansion ways. The way of direct extension was usually used than the one with the corridor, because it was more economical way.

This paper attempts to interpret the meaning of Mies van der Rohe's famous aphorism that "less is more" in terms of space. From his assertion that the art of building is the spatial execution of spiritual decisions, one can presume that his art of building was revealed through his spatial execution consciously guided by creative principles. One of his spatial principles was less is more a representative motto for the creation of sparsely furnished space with few objects and little perceptible architecture. After his awareness of an open plan, Mies intended to create less architecture by designing a minimal form of structural frames and maximum openness of open plans and glazed walls. This study posits that Mies created more potential space, for which he intended his open plans and neutral frames to be viewed as less. His building was designed to serve as the background of works of art and the changing nature outside so restrained its own existential voice in favor of the achievement of total harmony.

본 연구의 목적은 내진규준이 적용되기 이전에 건설된 역사건물의 내진성능 평가 및 내진보강이다. 이를 위하여 2층 RC 역사건물의 내진성능이 평가되었다. 동적해석에 의한 층간변위비 및 층전단력 평가결과, 층전단력이 설계기준의 밑면전단력을 초과하는 것으로 평가되어 적절한 내진보강이 필요한 것으로 평가되었다. 내진성능 향상을 위하여 총 4개의 강재댐퍼가 사용되었다. 해석 변수는 강재댐퍼 형상 및 설치 방법이다. 동적해석결과 역 K가새로 설치되는 슬릿댐퍼가 다른 댐퍼 형상 및 설치 방법보다 우수한 내진성능을 가진 것으로 평가되었다.

This study investigated the maintenance and management of government office building in Dongnaebu, Gyeongsangdo in the mid-19th century. In the late Joseon Dynasty, Dongraebu was an important point of national defense and a place of trade and diplomacy with Japan, so it had many government facilities. There are very few government facilities remaining today, and no structure remains. Therefore, it is possible to grasp information about the government facilities through the old materials. Currently, there are public documents related to the local government offices such as Eupji, Eupsarye, and Junggi. Through comparison between public documents, we will examine the maintenance and management of Dongnaebu government facilities in the mid-19th century. As a result of the research, Dongnaebu government facilities were supervised by department and managed like articles. In addition, the name, size, and changes were all recorded in the management of the goods, and the authority of responsibility was clearly stated. This result is because the remaining material has the purpose of preparation as an accounting book. As a result, it was found that the government facilities in the late Joseon Dynasty were managed by a systematic department with clear authority.

This study identifies efficient earthquake intensity measures (IMs) for seismic performances and fragility evaluations of the reactor containment building (RCB) in the advanced power reactor 1400 (APR1400) nuclear power plant (NPP). The computational model of RCB is constructed using the beam-truss model (BTM) for nonlinear analyses. A total of 90 ground motion records and 20 different IMs are employed for numerical analyses. A series of nonlinear time-history analyses are performed to monitor maximum floor displacements and accelerations of RCB. Then, probabilistic seismic demand models of RCB are developed for each IM. Statistical parameters including coefficient of determination (R²), dispersion (i.e. standard deviation), practicality, and proficiency are calculated to recognize strongly correlated IMs with the seismic performance of the NPP structure. The numerical results show that the optimal IMs are spectral acceleration, spectral velocity, spectral displacement at the fundamental period, acceleration spectrum intensity, effective peak acceleration, peak ground acceleration, A95, and sustained maximum acceleration. Moreover, weakly related IMs to the seismic performance of RCB are peak ground displacement, root-mean-square of displacement, specific energy density, root-mean-square of velocity, peak ground velocity, Housner intensity, velocity spectrum intensity, and sustained maximum velocity. Finally, a set of fragility curves of RCB are developed for optimal IMs.

The construction method of scaffolding structures is different from Mortise and Tenon and bucket arch structure of traditional large woodwork. It forms an independent construction system-fixing nodes with knots, a large number of diagonal braces are used to fix shelves and the structures mostly contain X-shape and triangular shape details. Simple ones include stalls, sheds, rain sheds, altars, lamp racks etc. But the scaffolding with larger scale and more complicated structure are modeled on archways, theatres and other buildings which are used in commercial and festival activities. At present, Macao, Hong Kong, Guangdong, Sichuan, Shanxi and other places in China have retained the custom of using scaffolding structures in important festival activities, but their uses, techniques and building types are slightly different from place to place. Due to building and demolishing at any time, the construction and service cycle is short. As a result, there are almost no physical objects left. We can only deduce the use and technical characteristics of ancient scaffolding skills through the colorful building styles that have been preserved with folk activities in various parts of China, the craftsmanship handed down from generation to generation by the scaffolding guild and artisans, and the description of cultural and historical materials and the mutual corroboration of visual materials.

Many RC building structures of multiple uses constructed in Korea have the irregularities of torsion and soft story at bottom stories. A typical irregular building was selected as prototype and shaking table tests were performed to investigate the seismic performance of this building. The objective of this study is to evaluate the correlation between the experimental and analytical responses of this irregular building structure subjected to the earthquake excitation by using OpenSees(Open System for Earthquake Engineering Simulation). The results of analyses simulate well the effect of axial forces on the shear force of column and axial deformation. However, some discrepancy between analytical and experimental results in the distribution of shear forces and overturning deformation were observed.

The wind load on building surface is numerically investigated. The geometry of target building is a square cross section and aspect ratio (height (H) to width (d)) is 6. On building surface, the pressure was measured, compared to obtained value from numerical simulation. The numerical simulations were done using URANS with three different turbulence models such as v2-f model, k-${\omega}$model, and k-${\varepsilon}$ model, respectively. The v2-f model showed the best agreement with experimental data in simulating mean pressure coefficients on front, rear and side surface. But unsteady characteristics of pressure history measured on surface is shown a discrepancy between experiment and numerical simulation.
