플랫 플레이트 구조의 외부접합부는 편심전단에 대해 비대칭형의 위험단면을 가지고 있으며, 위험단면의 길이가 내부접합부 보다 작고 중력하중과 횡하중 모두에 의해 편심전단응력이 발생하게 되므로 뚫림전단파괴에 대해 대단히 취약하다. 외부접합부의 거동은 대단히 복잡하며 또한 구조해석에서 사용하고 있는 강도모델이 부적합하기 때문에, 현 설계기준은 실험결과를 정확히 설명하고 있지 못하다. 본 연구에서는 이러한 현 설계기준의 미비점을 보완하기 위하여 슬래브-기둥 외부접합부에 대해 비선형유한요소해석을 수행하였다. 외부접합부에서는 횡하중의 재하방향에 따라 거동 및 최대강도가 상이하며, 해석결과에 근거하여 하중재하방향 별로 외부접합부에 대한 강도모델을 제안하였다. 제안된 강도모델은 실험결과와의 비교를 통해 검증되었다.

The purpose of this study is to extract the rage on exterior colors of Elementary schools in harmony with natural colors as the colors of sky and trees, of Which the colors is basically composing the natural environment. The theory of harmony in NCS relatively expressing the changed colors according to the color stimulation condition is the contrast of same color fit for the nature. NCS has a systematic open mind considering parts in the whole. The study suggests appropriate strategy for Eco-color scheme. The result shows that it's desirable to select YR Group in the elementray school of exterior color design, The Eco color planned by NCS is expected to clarify the interrelationship between children and environment. This practical use should be continuingly tried in the color design of interior for elementary schools.

This study was intended to investigate the contemporary meaning of transparent design expressed in contemporary fashion by inquiring into its plasticity expressed in contemporary design and fashion and analyzing the association between them. It used the comparative anesthetic method widely used by H. W lfflin and other scholars in eliciting the differences and similarities in styles. It attempted to investigate the plasticity of transparent design expressed in contemporary design by dividing it into the epidermal, spatial and ideological effects. Contemporary design expressed the epidermal effects such as lightness(nimbleness), smoothness, contrast and stress It expressed the spatial effects such as spatial flexibility through the interpenetration of interior and exterior spaces, expansion of the space and the like. And it expressed ideological effects such as openness, pureness, playfulness and the like. In terms of lightness, contemporary design expressed actual or visual lightness by using transparent materials. In terms of the interpenetration of interior and exterior spaces, it expressed the interpenetration of the interior space into the exterior spaces and vice versa. In terms of spatial expansion, contemporary design expressed the infinite spatial connection by drawing the exterior space into the interior space. Contrast and stress were formed by imposing visual unity on contemporary fashion by using opaque and transparent materials. In terms of openness, contemporary design expressed contemporary people's candor and dependability by making the inside of the building or object look outward. To express pureness, contemporary design used the clear and transparent image by using the glass or translucent materials taking on the pure property. To express playfulness, contemporary made use of the vagueness of the spatial boundary, the locational switching of inner and outer spaces, and interesting external forms occurring when light pass through opaque and transparent materials.

An experimental study was performed on the Pull-out behavior of 90-deg standard hooks from the exterior beam-column connections. the effects of the number of hooked bars and fiber reinforcement of the joint area were investigated with the following conclusions : (1) Under the pull-out action of hooked bars. the damage and cracking of joint area the number of hooks pulling out from a joint increases; (2) Substitution of the transverse column (confining) reinforcement with steel fibers at the joint region effectively reduces the extent of cracking in exterior joints caused by the pull-out of hooked bars; (3) The pull-out strength and post-peak ductility of hooked bars are adversely influenced by the increase in number of hooks pulling out from an exterior joint. Current hooked bar anchorage design guidelines may be improved by considering the effect of the number of hooked bars on anchorage conditions at the exterior joints; and (4) The strength and ductility of hooked bars under pull-out forces are positively influenced by substituting the conventional confining reinforcement of exterior joints with steel fibers . The application of steel fibers to the exterior joints is an effective technique for improving the anchorage conditions of hooked bars, and also for reducing the congestion of reinforcement in the beam-column connections.

In today's society, Monolithic expresses itself as a single featured work with a consistent exterior in the urban environment. In particular, such characteristics of the monolithic work have become increasingly influential in the modern society with the emergence of the minimalism. Monolithic architecture in modern has common feature which is maintaining simple construction format (Mass) with complicated and abundance space (Volume) inside. This simple architecture exterior leads new stimulus which is different from previous format and evokes unique sensibility and thoughts with monumental expressing. Uniformed exterior revealed thru purity of material builds up strong presence by itself. In contract with simple exterior, diverse space is expressed by consistent concept and process. Through this, it shows creating metaphorical space and space-oriented feature. We can interpret modern monolithic architecture as a sensation and alternative against Gestalt architecture in consequence of chasing clarity, visual stimulus and uncertain tendency only. It provides architectural experience by spatial imaginary and unexpected space development to users through exclusivetendency against outside and stressing un-private, we can evaluate its value as a space-oriented construction which helped us to think about space meaning in modern society.

It is the urgent task of induce the inhabitants to utilize the public transportation instead of the personal transportation to dissolve the traffic jam. But construction of the subway, the representative substitute means, demands a great of investment expense including various kinds of expenses. So the technical development and research of standardization of FRT(Fuel cell Rubber tired Train), the eco-friendly public transportation system low in construction expenses, effective, excellent in approach as well as in traffic, are propelled positively. This project wants to propose exterior design FRT in which original creative methods are utilized with the target of development and construction of FRT which coincide with anthropocentric eco-friendly traffic system. Utilizing the proposed style as the basic materials, this project wants to grasp difficulties, and to establish the way to solve and develop them.

The purpose of luminance measurement in lighting design of urban scale is to prevent light trespass and light pollution, caused by over-bright. Specially, the illumination of road, tunnel and sports complex as urban infrastructure is measured by international standard for illuminance and luminance. It has been used the spot luminance meter and the image photometer to define the characteristics of qualitative and quantitative in exterior lighting. This study introduced the concept of HDR Image, procedure of HDR Image creation and analysis. Applications of HDR Image, particularly within the apartment building exterior lighting design analysis, have been demonstrated. The procedure proposed in this study is a affordable method that is useful for the assessment of luminance distribution in the scene with electric light. It also provides a measurement capability with the high resolution luminance data within a large field of view efficiently and quickly, which is not possible to achieve with a luminance meter.

Exterior beam-column joint is typically the weakest link in a limited-ductile reinforced concrete (RC) frame structure. The use of diagonal haunch element has been considered as a desirable seismic retrofit option for reducing the seismic demand at the joint. Previous research globally has focused on implementing double haunches, while the use of single haunch element as a less-invasive and more architecturally favorable retrofit option has not been investigated. In this paper, the key formulations and a design procedure for the single haunch system for retrofitting RC exterior beam-column joint are developed. An application of the proposed design procedure is then illustrated through a case study.
