The purpose of this study was to evaluate the material characteristics of SHN400 steel, which is suitable as a steel material for building structures, using the experimental approach. For this purpose, the chemical composition test, tensile test, macro test, micro test, and charpy notch impact test were conducted with specimens taken from the highest, thickest, and commonly used H-beams for girder or beam members. Each test was conducted under the Korean Standard(KS) test conditions. All the test results satisfied the requirements of KS (KS D 3866) and the steel material for seismic design. The carbon equivalent value (Ceq), which is related to weldability, and the yield ratio, which is related to inelastic behavior, showed especially good results. Thus, SHN400 is definitely suitable as the steel material for building structures.

A modern architectural building is a cultural heritage, which is also part of our history until the present. Documentation is thus considered an irreplaceable method to preserve our cultural heritage as it may be the last resort of preservation. The study analyzed the Historic American Buildings Survey (HABS) on the Heritage Documentation Programs of the National Park Service. Based on the analysis of the comparison and documentation of the modern architectural building implemented by the Cultural Heritage Administration, the study suggested improvement plans from three different perspectives. First, specifically detailed regulations of the legal system are supposed to be used for the implementation of the documentation of modern architectural buildings. Second, it is suggested that a general plan for continuous documentation be made. Last, by setting up a collection method, an information service needs to be provided for the public.

The buildings constructed with steel structure are coated with certified fire resistive material to resist from fire. All the building materials lose their initial performances as time passes by, so they need some maintenance. The Sprayed Fire Resistive Material (SFRM) also loses its performance and this performance loss of the SFRM is very important because fire resistance of buildings depends on SFRM. So this study was aimed to synthesis of alkali-silicates for SFRM and to evaluate the effect of alkali-silicates, K-silicates, Na-silicates and Li-silicates, by exchange of mole ratios as basic factors, tested solubility, intumescence ratios, thermal analysis, powder X-ray diffraction, fire-resistant and heat-resistant.

The purpose of this study is to identify the architectural design elements of secondary shrines in traditional Buddhist temples in Korea. For this study, a survey of six kinds of secondary shrines (Myemgbujem, Yeongsanjeon, Eungjinjem, Yaksajeoun, Gwaneumjeon, Mireukjeon), according to specified design elements(building sizes, roof styles, Gongpo, Dancheong, shape of Datjip), was conducted. The results of this study are summarized as follows; Myeongbujem is built in every temples(25 examples), most having simila1ities in sizes and architectural elements(roof, Gongpo structure, Dancheong, Datjip). The majority of Yemgsanjeon(l4 examples) and Eungjinjem shrines(l5 examples) are mostly 3-Gan sized buildings, having a Matbaejibung and Ikkmg structural system. Gwaneumjeon, on the other hands, has 1he most elaborate architectural elements. Among 12 cases, 8 buildings have Paljakjibung, 9 buildings have Silk-Dancheong in innerspace, and Datjip are included in six buildings. Yaksajeon shrines are small in mnnber, but most of these shrines have a Dapo structure, and, despite of their size, are designated as cultural properties.

This research is intended to suggest some reference materials for the future planning of floating hotel, by reviewing the concept of floating hotel and analyzing the realized and planned ones through the search of related documents and homepages. Floating hotel can be defined as a building for living/recreation/work/entertainment with floating system on water, but without navigation tool. In terms of sequence, the River Kawi Jungle Rafts Resort was built in 1976, Four Seasons Hotel in 1988, and Salt & Sill in 2008. Floating hotels are various in scale(height) and size(room numbers), and have basic, cultural, health & marina facilities. Architectural characteristics of sample facilities can be summarized as self-supporting of the facilities, environmentally friendly architectural planning, utilization of renewable energy, introduction of new plastic composite material, and provision of same view from all bedrooms by rotating the building.

10년도 넘었을까 모처럼 유럽을 여행할 기회가 있었다. 우리나라는 온 국토가 공사장이나 진배없던 시절이라 그곳의 풍경이 오히려 이채로웠다. 자동차를 타고 한참을 가야 그것도 별로 크지 않은 공사장을 볼 수 있었고, 그나마 신축공사 보다는 오래된 건물을 보수하는 것들이 더 많았다. 더구나 희한한 것은 대로에 면한 고색 창연한 건물의 외벽만을 텔레비전 세트처럼 남겨두고 그 뒤편에서는 전혀 새로운 공사를 하는 것도 눈에 들어왔다. 조상들의 유적을 외관만이라도 보존하도록 법제화되었으므로 여기저기 떨어져 위치한 100년도 넘은 집에다 따로따로 최신형 공작기계를 설치한 공장에서 제품을 생산하는 비능률을 감수하는 것도 볼 수 있었다. 물론 변두리 신시가지에서는 현대 감각이 물씬한 건물도 신축하고 있었는데, 대체로 리모델링 사업규모가 전체 건축 물량의 50% 정도는 될 것이라는 설명이었다. 필자는 그때 우리도 머지 않아 그런 시절이 도래할 것이라는 확신이 있었다. 더구나 그들의 건물들이 100년 이상을 버티는데 반하여 우리네 것들은 수명이 고작 20~30년 밖에 되지 못할 정도로 부실하기 때문이다. 그때부터 기존 건물의 내력 부족분을 보완하고 용도를 변경하거나 증축을 할 때 어떤 방법이 합리적일까 하는 것에 관심을 가지고 연구하게 되었다. 바닥 슬래브나 보를 잘라버리거나 새로 덧붙이기도 하고 심하면 기둥을 솎아낼 필요가 있을 수도 있다. 그러나 유감스럽게도 대부분의 경우는 그동안 열심히 고안한 방식을 실무현장에 적용할 수 있도록 받아들이는 당사자가 별로 없었다. 첫째 이유는 처음하는 일이라 말하자면 겁이 난다는 것이고, 둘째로는 새로운 방식을 믿고 시행하려 해도 실제로 책임지고 시공하겠다고 나서는 업체를 만날 수 없어서였다. 그래서 그동안 설계뿐만 아니라 시공까지 일일이 간섭하여 어렵게 시행했던 현장 경험들을 소개하여 앞으로 비슷한 조건을 만날 경우 참고할 수 있게 한다. 우선 기둥을 솎아 내는 것을 알아보고 앞으로 기둥, 보, 슬래브, 기초 등의 새로운 보강방법을 소개하고자 한다.

In order for efficient recycling and eco-friendly treatment of construction waste, there is a need to apply a building separation and dismantling technique early on in the stage of waste generation. This study was conducted to analyze the relevant domestic circumstances and propose the applicable range of buildings in order to introduce a building separation and dismantling system to Korea. For this purpose, related policies and systems implemented overseas and the current situation of buildings were examined, and the workability of separation and dismantling of buildings according to their uses was compared. Also, the economic impact of the separation and dismantling system was examined and a survey was conducted, seeking the opinions of the relevant companies regarding the need for the system and the selection criteria for eligible buildings. Based on the results, it was determined that it would be impossible to apply the separation and dismantling system to all buildings in Korea, considering the current technical power and economic situation, and that the system should be introduced in phases, according to the building classification determined based on floor area and use, as the cost may vary depending on a number of variables including the level of difficulty and field conditions.

본 논문에서는 컴퓨터 비젼의 사진측량학적 방법과 대상물의 기하학적 정보를 결합하여, 사진으로부터 건축물의 정확한 값을 복원해 내는 새로운 모델링 시스템을 소개한다. 사용자의 간단한 프로토타입핑으로 얻은 대략의 모델 정보를 시스템이 사진 이미지와의 오차를 최소화하는 방법으로 자동적으로 모델 정보를 복원해 내며, 사진에서 최선의 텍스쳐 맵을 생성해 내므로, 세밀한 모델링 없이도 사진 수준의 사실적인(photo-realistic)모델을 얻을 수 있다. 빠르고 간단한 방법으로 실재 대상의 효과적인 모델을 얻을 수 있는 이 연구의 성과는 가상현실 분야의 모델링 작업에서 추구하는 바와 일치하므로, 가상현실 분야에서 유용하게 사용될 것으로 보이며, 알맞은 대상에 적용을 통해 실질적인 응용이 기대되어진다.

The purpose of this study is to propose a decision-making technique for selecting waterproofing methods using the Analytic Hierarchy Process (AHP) technique. In this study, a questionnaire survey was given to a group of specialists, which included design specialists, construction specialists, and maintenance specialists, regarding their experience with roof waterproofing methods. The 1st level hierarchy of the questionnaire survey addressed the function, economics, and maintenance of each of the roof waterproofing methods. The rank of 13 items of questionnaire, which is the 2nd level hierarchy of the questionnaire survey, is calculated using Expert Choice Solution. The analysis of questionnaire survey shows that each specialist selects different roof waterproofing methods, and all specialists make much of waterproof performance.
