Architectural fabrics are now used in membrane structure with the merits of free shape, lightness and opened up new possibility for the design of new building structures. Recently PVC, PVF, PVDF, PTFE coated fabric for using the membrane structures. However, clear standards for the design and construction is not exist because of the lack of Architectural fabric research. In this paper, Flammable properties of PVDF, PTFE coated fabrics are obtained through the Flammability test using the Cone Calorimeter. Based on these results, identify the fire resistance property of the Architectural fabric.

The surface design in architecture plays a role as an indicator that symbolizes cultures and styles, in accordance with the course of history and the standards of the time. The surface design that determines the facade of an architectural structure allows us to have a more clear understanding about the functions, programs and structures, as well as the periodical concept of the architects than any other components of the architecture. The purpose of this paper was to examine how architectural surface designs were realized, using commonly-used materials. This study provides meaningful implications, in that it suggests common features in terms of design methodologies (between architecture and non-architecture fields), and presented new possibilities for contemporary architectural surface designs through the classification of building system methods depending on fabric properties, and through the case study analysis of architectural surface designs; in addition, the results of this study could be utilized as basic data for future studies on the possibility of the expression of surface designs across a broader domain.

Wind Turbines are becoming larger in size in order to improve economic efficiency through cost reduction, such as the construction of growth and power infrastructure of energy efficiency. It have requested the large-scale blade design and production. In the present study the new manufacture technique called a fabric-blade structure using spar, rib, and fabric membrane skin is introduced. The architectural membrane test method has been studied to be applied to the skin of the blade. The density and one-axis tensile tests of the architectural membrane materials are conducted to confirm the physical properties which are necessary to the structural designs and analyses of the wind turbine blade.

막구조 건축물은 경량의 건축용 막재를 사용하므로 자유로운 곡면표현이 가능하고 시각적인 만족도가 높아 그 사용이 점차 확대되고 있다. 하지만 건축용 막재를 구성하는 직물이 화재에 취약하므로 용도에 적합하며 보다 높은 난연성능을 가지는 불연성 막재의 개발이 요구되고 있다. 따라서 본 연구에서는 단열성, 내열성, 불연성이 우수한 현무암섬유를 건축용 막재의 직포로 적용하고 PTFE 분산 수지를 함침 코팅하여 DSC/TGA 열분석, 강도특성, 방염 및 난연특성을 평가하였다. 또한, 일반적으로 사용되는 건축용 막재 중 성능이 가장 우수한 유리섬유 직포 막재와 난연특성을 비교하였으며 평가결과 현무암섬유 직포의 건축용 막재로서의 가능성을 확인할 수 있었다.

We have focused on the building appearance according to the change of conservation policy and urban fabric in Bukchon, Seoul. The Urban Hanok, urban traditional housing type, had been evolved in modern contort from 1920's to 1960's, that is to say, many buildings(Urban Hanok) in Bukchon area has built up with a lot and road at the same time. But the change of conservation policy has an effect on the urban fabric and building(wooden structure, RC and brick building). Thus many types of building in Bukchon has undergone a various change. The purpose of this paper is to define a change factor of Bukchon buildings. Thus we need to pay attention to policy and urban fabric. We reached the result as follows. First, the change of architecture regulations according to the several policies(an aesthetic area, an altitude area for sky line restriction and so on) brought into building deformation and eventually the historic scenery of Bukchon has been spoiled. Second, the change of policy had an effect on the change of roads and lots. Buildings on a widen road and a united lot was built newly. But new buildings built up with a concrete or brick structure was not in harmony with the historic scenery of Bukchon area. Third, a development method of a large lot with lack prudence(disregarded a scale and size of lot) did damage to Urban hanok and urban fabric. With the understanding on the relationship of buildings, a urban fabric and a policy in Bukchon, we can define the identity and correspond with the urgent request for a the conservation of historic urban scenery In addition we can suggest the policy and the design guidelines for the reservation and rehabilitation for Bukchon, Seoul.

This study proposes a novel rotary direct evaporative cooler and investigates the potential of a moisture-wicking fabric as a cooling pad for the proposed evaporative cooler. The rotary direct evaporative cooler rotates the cooling pad to reduce the water and energy consumption of the pump compared to those of existing direct evaporative coolers. A moisture-wicking fabric is considered as the material of the cooling pad, because of its high moisture-wicking property, enhancing water evaporation. Experiments are performed under various inlet air conditions while measuring the air temperature, relative humidity, air velocity, and differential pressure. The evaporative cooling efficiency and impacts of the inlet air temperature and air velocity on the cooling performance are also evaluated. The results demonstrate the potential of the moisture-wicking fabric as cooling pad of direct evaporative cooler.

In this paper, a pressurized single vertical arch and a pressurized leaning arch composed of flexible fabric material are considered. These arches have also been considered as a possible support structure for the tent-like structures. Two different boundary conditions are considered in leaning arches with fixed bases and pinned bases. The behaviors of the leaning arches are investigated for two tilt angles as 15, 30. For each angle, two loading conditions are considered as uniformly distributed load and wind loads. The F.E.M. is used through the all analysis procedures. For the results, load-deflection relationships, buckling modes, differences between two boundary conditions and deformed configurations are discussed.

막구조 건축물의 시공 증가에도 불구하고 국내에는 내화 및 방화기준이 마련되어있지 않고 일반 건축물의 내화기준을 적용하고 있어 막구조 건축물과 막재료의 특성을 반영하지 못하고 있다. 또한 막구조 건축물의 내화 및 방염성능을 확보하기 위해서는 막재료가 규정된 난연성능을 만족해야 한다. 따라서 본 연구에서는 건축용 막재의 고온에서의 안전성을 확보하기 위해 현무암섬유를 직포로 적용하였다. 그리고 막재의 강도특성과 방염 및 난연특성을 기존의 건축용 막재와 비교, 평가함으로써 막재료의 평가기준에 대한 참고자료로 삼고자 한다. 연구결과, 현무암섬유와 유리섬유 기반의 건축용 막재는 낮은 열방출율과 총방출열량을 나타내 화재안전성이 높은 것으로 확인되었다.
