뉴미디어의 특성을 지니며 더욱 다양한 가능성과 관계를 열어나가게 된 오늘날의 현대 건축은 근대 이전의 구축적 양식 중심의 형식으로부터의 탈피, 디자인 분야의 심미적 발달, 자연 친화적인 관점으로의 발달, 그리고 무엇보다 인간 중심의 건축 발달 등으로 인해 구조, 실체와의 관련성 이외에 표면(surface)으로의 관심이 집중되면서 감상적인 공간 구조를 낳고 있다. 이는 표면이 공간적인 효과를 내는 표면을 통해 새로운 소통의 길이 열리게 되고 건축물 그 자체의 자율성을 표현하는 동시에 주변 컨텍스트에 동참하게 되므로 경계 영역으로서의 의미를 전달하는 인터페이스로 발전해 가고 있음을 시사한다. 또한 최근에는 더욱 적극적인 미디어 재료의 사용으로 건축의 표면이라기보다는 오히려 독립된 스크린으로써의 모습을 보여주고 있고, 그에 더해 다양한 미디어 아트 작업의 차용으로 표면의 스크린화는 더욱 진화하며 이전과는 또 다른 효과와 의미를 전달하고 있는데, 이는 공간 사용자의 능동적인 수용 형태를 인지하고 건축을 완성하는데 있어서 중요한 주체가 됨을 시사한다. 본 논문에서는 이러한 건축 표면이 가진 인터페이스로서의 특성과 최근의 적극적인 미디어 재료 사용 및 미디어 아트 차용을 통한 다양하고 새로운 소통의 시도를 분석해 봄으로써 건축 표면이 가지는 더욱 넓은 범위에서의 가능성과 잠재력을 건축 그 자체가 가지는 특성 안에서 뿐만 아니라 수용자와의 상호관계 안에서 또한 연구해 보고자 하였다.

The research efforts to modernize Hanok (Korean traditional housing) have been performed to improve the quality and cost-effectiveness through application of modern building methods and materials, and to disseminate it in various forms of sizes and facilities. In this study, in order to identify the variations of modernized Hanok, data from seven test-bed projects are analyzed based on the building work-section, element, method, and material. The data were standardized and managed through the modernized Hanok classification system (Hanclass) to facilitate systematic comparisons of the test-bed projects by the variation of building method and it's cost impact. Identified factors of the variation in terms of building methods were then itemized and quantified in terms of building cost. Findings of this study indicate that the timber structure is the most critical area for future variation for improving the quality and cost-effectiveness. The results of this study will be also used to systemize the Hanok database for further studies.

As Additive Manufacturing (AM), so-called 3D printing technology, has become visualized, its potential for Mass-Customization, production costs and time savings has extended the scope of utilization to the architecture domain. Several cases that produced facilities, building elements and components using 3D printing technology have been announced mainly on the outside. There is also the development of foundation technologies including 3D printing-specific materials and equipment in Korea. As 3D printing technology in the architecture domain is currently in the early stages of adoption, realistic and systematic strategies are needed to advance it to the commercialization stages, considering the current circumstances of the industry. With this background, this study surveyed experts to investigate the status of the perception of 3D printing technology for adoption in domestic architecture industry. 3D printing technology is expected to be commercialized in areas of irregular-shape buildings and interior markets rather than general construction area. 3D printed products expected to be commercialized are limited to the level of building elements and the aesthetic factor is regarded as the most competitive factor. To enhance the possibility of the commercialization of 3D printed products, the 3D printing-specific construction method, related policies and systems are required along with the performance and stability of the materials and equipment.

건축디자인 초기단계에서 다이어그램은 아이디어 및 디자인 해결방안을 도출하기 위한 분석 도구로써 중요한 의미를 지닌다(Wang, 1999; Do, 1997). 이러한 다이어그램은 시각적 디자인 피드백을 가능하게 함으로써 건축디자인 실무 및 교육에서 필수적인 디자인 도구라고 할 수 있다 (Schon and Wiggins, 1992; Gross, 1996; Kurmann, 1998). 최근에 IT 기술이 건축분야에 적용됨에 따라, 건축가들의 전통적으로 고려되어 왔던 인간의 행동, 자연현상, 건축재료, 건축부재, 대지조건 외에 다양한 IT 기술과 관련된 정보를 분석하고 고려할 필요성을 가지게 되었다. 그러나 이러한 다양한 IT 기술은 건축적인 요소들과 접목되어 적용되기 때문에 건축가들은 디자인 초기단계부터 IT 기술의 접목이 가능한 디자인 도구를 필요로 하게 되었다. 즉, 이는 IT 정보와 공간정보와의 관계 및 적용을 건축가가 빠르게 이해하고 분석하고 이를 디자인에 반영할 수 있도록 도와주는 시각적 다이어그램 표출이 가능한 디자인 도구가 필요하게 되었다. 본 논문에서는 다양한 IT 기술과 공간 정보의 다양한 형태의 관계를 나타내는 3 차원 버블 다이어그램을 이용한 계략 디자인 방법을 제안하고, 이를 기반으로 3 차원 버블 다이어그램을 지원하면서 건축 디자인 초기단계에 이용 가능한 디자인 도구를 개발한다. 본 연구에서 개발된 디자인 도구는 정보의 유형에 따라 다양하게 형태를 변화시킬 수 있는 노드(node)와 연결선(edge)로 구성되고, 저장된 특정 건축정보는 다이어그램으로 생성된 디자인 대안을 평가하는데 사용된다. 일종의 DSS(Decision Support System)인 본 시스템은 디자인 초기단계에서 3 차원 디자인 아이디어를 제공할 뿐만 아니라 다양한 디자인 대안을 빠르게 생성하고 이를 실시간으로 평가함으로써 디자인 효율성을 증가시킬 것이다. 본 시스템은 유비쿼터스 기술이 적용된 신도시에 생성될 통관관제센터 디자인에 실험적으로 적용되었다.

In Korean traditional wooden architecture, joint performance varies with the material characteristics of timber, the form of joint, the precision of timber-trimming and the like. Case studies prove that the beam-to-column joint type has large influence on the degrees of deformation and spacing. This is not only true of single-story buildings, but also of large-scale multi-story buildings more apparently. Therefore, this study followed the process of examining to joint types, producing their specimens and testing their structural performance. As a consequence of structural test, the dovetail joint specimen showed the best outcomes of the maximum load and rigidity. Synthesizing the structural performances by respective forms of joints, the Doraegeoji dovetail joint specimen showed the higher performance, followed in order by the Doraegeoji mortise joint specimen and the Tongneoko dovetail joint specimen. The structural performance of a building varies with the characteristics by the shouldering forms of penetrating beams and with the joint types within the columns. This should be considered for the new construction or restoration of multi-story buildings, and be continuously researched henceforth.

In today's diversified society, it is hard to know which building style represents the architectural style of the time. The simplicity found in monolithic-style buildings forms a symmetrical point with fairly complex structure, and its value can be acknowledged. This study analyzes buildings made of insulating lightweight aggregate concrete in the early 21st century, defines the concept of monolithic expression, and examines how these characteristics are expressed in the space, forms, and structural methods in construction. Unlike a multi-layered exterior wall system, which features multiple layers composed of a variety of materials, the exterior walls built with insulating lightweight aggregate concrete comes in a lump form with a mold form that is tightly filled with concrete as a single material and is monolithic. This is attributed to the creation of spaces characterized by the homogeneity of inner and outer spaces with the use of the same material, continuity of the surface as solidity, spatial characteristics of the stereotomic construction, expression of materiality with the use of exposed concrete, and the contrast of the lump and the space. This not only reveals formal characteristics that expose a discourse about monolithic architecture in contemporary architecture but also provide an opportunity to extend the range of discussion to structures and materials and even to their effects on space.

지진에 대한 건축물의 확률적 성능평가에 대해서는 지진하중에 대한 건축물의 손상확률 또는 파괴확률을 나타내는 지진취약도 함수를 작성하여 대상 건축물에 대한 지진위험도를 평가하는 방법을 이용하고 있으며 이에 대한 많은 연구가 이루어지고 있다. 본 연구에서는 지진하중과 구조물 재료특성의 불확실성을 고려하고 대상 건축물의 지진취약도 해석을 통하여 비내력벽의 유무에 따른 건축물의 지진거동 및 내진성능을 평가하였다. 비내력벽을 보편화된 모형화 방법인 등가의 대각 압축 스트럿으로 고려하여 비내력벽의 유무에 따른 저층 철근콘크리트 건축물을 모형화하였으며 지진하중의 강도는 유효최대지반가속도를 이용하여 각 건축물에 대하여 지진취약도를 작성하였다. 취약도해석 결과로 연약층을 가지고 있는 건축물의 경우는 손상확률이 골조만 있는 경우보다 크며 동일한 해석모델의 경우에도 해석방법에 따라서 취약도 곡선의 형태가 다름을 알 수 있었다.
