A recent global trend in the increase of earthquake-related disasters has become so frequent as to cause various damages to a wide range of mid- to high-rise buildings. Particularly, more attention is being paid to the effect of horizontal load in high-rise buildings not only on the key structural elements of the structures, but also on the possibility of the secondary damages to them due to the failure of exterior panels, which are non-structural elements, but such damages are difficult to cope with as they may be caused by unexpected changes. The present study examined exterior panels using moving clips to prevent such secondary damages on the non-structural elements and analyzed the structural performance of these exterior panels through the finite element analysis and the shaking table test. The analysis results showed that the exterior panels using moving clips satisfied the structural performance against the allowable story drift of KBC2009 and the safety of the exterior panels was verified by the shake table test.

To investigate the cyclic characteristics of the retrofitted exterior joints of RC frame with haunch, 70% scaled 6 beam-column exterior joint subassemblies were designed according to design guideline according to 1988 and tested with cyclic loading up to 3.5% story drift ratio. During the experiments axial forces are applied to columns to simulate gravity load. Experimental results shows that the strength of retrofitted specimens was increased steadily until 2.5% story drift ratio and their strengths increased more than 1.7 times of the non-retrofitted in case that main bar was bent away from exterior joint. The joint strength and effective stiffness of the retrofitted specimen was increased and results in more deformation capacity compared to the non-retrofitted.

The purpose of this study was to analyze the characteristics of exterior look and interior space of Boutique hotels in Prague and to identify how the tradition and the modern styles were integrated in each element. The subjects of this study were 12 tradition and modern style integrated hotels in Prague. From the collected data, the followings were investigated; what are traditional and modern elements, how they are integrated, and what the ratio of the tradition and the modern style is. The results are as follows. First, regarding the level of integration of tradition and modernity in Boutique hotels in Prague, exterior look showed conservativeness and interior space showed innovation. Second, in the conservative combination of exterior look, the traditional facade made conflicts with the modernity of the signage but the expression was limited to the modern expression of façade and signage maintaining the traditional form. Facades were modernized with the limitation such as not to interfere its traditional atmosphere and signs were designed to be compatible with facade. Third, in the innovative integration between the traditional and the modern of interior lobby, they partially maintained traditional elements or reinterpreted the traditional elements in modern terms in ceiling, walls, columns and windows and used modern expressions in most of ornamental elements.

In general, the entire air supply of a bio-safety laboratory (BSL) should be exhausted on the outside to ensure bio-safety, and the air conditioning system should always be operated to maintain a difference in the room pressure. As a result, the annual energy consumption of such a building is approximately five or ten times higher than that of an office building of the same magnitude. Thus, this study applies an actual operating system that targets BSL. The energy consumption is analyzed using the Energy Plus V8.0 program (an energy analysis program), and five kinds of cases that depend on the energy consumption of the basic BSL system are also analyzed. As a result, the energy consumption in Case 1 (basic system) is of 324.95 GJ. When the basic system of Case 1 is compared to that in Case 2 (basic system+passive design with exterior envelopes), an annual energy savings of is 6.9% is achieved. For Case 3 (basic system+Photovoltaic, PV) 12.7% is achieved, and for Case 4 (Solar Geothermal Hybrid System of renewable energy, SGHS) 49.5% is achieved. If a passive design with exterior envelopes and renewable energy system (PV+SGHS) is combined, as in Case 5, the energy consumption would be 118.15 GJ. Therefore, when this last system is compared to a basic system, the passive design with exterior envelopes and renewable energy system (PV+SGHS) can reduce energy consumption by 63.6%.

For lighting design in such diverse structures, we need lots of considerations, such as use and characteristics of the structure, harmony with its surroundings, and the function and type of lighting to be installed. The structural characteristics is determined by its shape and several vertical and horizontal factors based on the shape, which can be focused on at day time by shading, the surface structure, the quality of the surface and the color. On the other hand, they can be at night hidden in the darkness or enforced strongly by the effect of the lighting. In this paper, correlation between the ways of lighting and building facade types according to vocabularies for sensitivity is explored based upon an analysis of building facades for small-scale commerce which plays an important role in cityscape lighting design. It is considered that categorization of types of building facades, presented in this article, and the classification system of exterior lighting methods can be useful in planning lighting. And the process of the study is thought to be able to present a method about the exterior lighting planning. Furthermore, computer simulation on the bases of the correlation model of the lighting methods related to vocabularies for sensitivity about the building facade types is expected to be data and means which can be a great help for designers to predict various results quickly.

This study aims to inspect changes of physical expression in surfaces of both building interior and exterior in contemporary architecture. Nowadays society has transformed into more complicated framework with the development of the new media and digital technology in 21 century. Surface's expressivity has been changed with design trend and material development. Although surface study has been mainly concentrated on properties of materials and structure characters, new technology and cultural acceptance enables it extend itself to a new area with various design methods, taking its place as an important contemporary architectural element. Interior surface design is expressed with several unique methods such as optical illusion, surface exposure and spacial depth and volume, and it created dynamic space within the surface itself. In case of exterior surface, whole space seems to be designed to be coordinated with structured optical illusion as well as symbolic expression. Surface's area is extends itself with the stream of the times. This study explored the nature of surfaces with categorizing and comparing them in a various views and methods.

In the present study, exterior beam column sub-assemblages are designed in accordance with the codal stipulations prevailed at different times prior to the introduction of modern seismic provisions, viz., i) Gravity load designed with straight bar anchorage (SP1), ii) Gravity load designed with compression anchorage (SP1-D), iii) designed for seismic load but not detailed for ductility (SP2), and iv) designed for seismic load and detailed for ductility (SP3). Comparative seismic performance of these exterior beam-column sub-assemblages are evaluated through experimental investigations carried out under repeated reverse cyclic loading. Seismic performance parameters like load-displacement hysteresis behavior, energy dissipation, strength and stiffness degradation, and joint shear deformation of the specimens are evaluated. It is found from the experimental studies that with the evolution of the design methods, from gravity load designed to non-ductile and then to ductile detailed specimens, a marked improvement in damage resilience is observed. The gravity load designed specimens SP1 and SP1-D respectively dissipated only one-tenth and one-sixth of the energy dissipated by SP3. The specimen SP3 showcased tremendous improvement in the energy dissipation capacity of nearly 2.56 times that of SP2. Irrespective of the level of design and detailing, energy dissipation is finally manifested through the damage in the joint region. The present study underlines the seismic deficiency of beam-column sub-assemblages of different design evolutions and highlights the need for their strengthening/retrofit to make them fit for seismic event.

버스외부광고는 매체의 특성상 도시를 운행하며 불특정 다수에게 노출된다는 특성이 있다. 이는 단순한 기업의 이익을 위한 사적인 마케팅 활동을 넘어서서, 도시의 공공성에 영향을 미치게 된다. 서울시는 시내 버스 외부광고 운영 개선 계획을 통해 주류 및, 담배, 선정적 내용의 광고들이 점차 사라지고 있는 추세이나 공공성의 관점에서 살펴보아야 할 광고들도 여전이 있었다. 영국의 버스외부광고 현황 및 사례를 통해 버스 외부광고의 높은 노출성과 광고효과로 광고가 활발히 이루어짐을 알 수 있었다. 또한 버스외부광고 내용의 지침서를 정해놓고 관리 감독을 하고 있어 공공성 부분을 중요하게 다루고 있었다. 버스외부광고의 공공성을 '영역의 공공성', '주체의 공공성', '이유의 공공성', '절차의 공공성'으로 분류하여 그 의미를 설정하였다. 이를 통해 버스외부광고에 대한 적절한 규제 및 관리가 이루어질 때 사적인 영역인 버스외부광고의 상업적 권리와 시민의 권리인 공공성이 적절히 조화롭게 발전할 수 있음을 제언하였다. 도시환경관점에서 버스외부광고를 통한 예술적 접근이 미적향유와 시민의 디자인적 눈높이 향상에도 일조한다.
