Recently, the demand of the large span structures has been increasing. The large span structures include such a large scaled structures such as: the shell structure, the space frame structure, the membrane structure and the cable structure, etc. The large span structures are supposed to be confirmed and issued carefully at the initial process of the design besides the construction engineering aspects because of the structural specific cause that should solve and accomodate those large and wide space without columns. In the field of the large span structure construction, the erection construction method has been regarded as a major affected aspects on the construction cost, construction term, and stability. In the field of the large span structure construction, there are various construction method and system could be applied depends on the condition of the construction site and other circumstances such a major construction method as: the element method, the block method, the sliding method, the lift-up method and complexed method, etc. In this study, as the case study of the erection construction method of the large span structures, after survey and study that those existing large span structures construction cases which had applied and adopted the election construction method and analysis and classify into the Uoups by the size, span, ceiling height, structural system in odor to supply and suggest the data for the enhancement and development in the field of the erection construction method as a efficient structural solution of the large span structure construction.

대공간의 건축물의 합리적인 설계를 위해서는 온도 및 기류분포의 정확한 예측이 필요하다. 예측 방법으로 정밀해석 모델(CFD)만을 최선의 방법으로 생각하는 경우가 대부분 이지만, 비용과 시간을 줄이기 위해서는 설계 단계별로 보다 적합한 예측 방법을 적용 할 필요가 있다. 이것은 다양한 예측 모델들의 장·단점 및 실용성에 대한 충분한 이해가 전제될 때 가능할 것이다. 본고에서는 열환경·설비 설계시, 설계 단계에 따른 적합한 예측 모델들을 소개한다. 더불어, 적절하고 타당한 예측 기술이 설계에 반영되어 대공간 건축물의 실내 열환경 개선 및 에너지 절약이 이루어지기를 기대한다.

현재 도시의 발달은 건축물의 대형화와 다양화를 생활 필수 요소로 정착시켰으며 이는 공항, 역사, 체육시설, 전시시설을 비롯하여 여러 시설을 대형화 시켰다. 또한 급속도로 발전해온 국내 건축물의 대형화에 있어서 사고 및 피해는 건물이 고층화되면서 발생한 1971년 대현각호텔 화재사고와 같이 상시 발생가능성이 있는 대형화재의 위험성을 가지고 있다. 본 연구는 국내외 대공간 건축물의 화재 사례를 data base화하여 화재발생 확률 및 빈도를 분석하였다. 이러한 분석 결과는 화재발생가능성이 있는 대공간 건축물의 화재 시나리오 작성 및 대처방안 정립에 기초자료로 사용될 것으로 평가된다.

For the large space buildings since 1960s in Korea spanned more than 30m, the establishment feature and the development process were examined. As the Results, physical facilities with 40-70m span were mainly established in 1980s-1990s, but large scale convention centers have been establishing after 2000s as the used of large space buildings are varied. Also, a space frame has been generally used in 1980s while the unique structural shapes were builded in the early age(1960s), the structural design with concerns a form and using various structural systems have been attempting after 2000s.

비정형의 대공간 구조물은 대량의 부재가 규칙성을 가지고 공간상에서 반복되는 패턴을 가지는 특징이 있다. 이러한 특징은 기존의 구조해석 모델러로부터의 접근을 어렵게 하는 반면, 관계성과 규칙성을 논리적으로 모델링함으로써 최종 모델을 생성해내는 파라메트릭 모델링 방법에는 매우 적합하다. 본 연구에서는 이전의 연구를 통해 개발된 파라메트릭 구조해석 모델링 툴인 STRAUTO을 이용해 전형적인 비정형 대공간 구조물인 용인시민체육공원 주경기장의 모델링에 파라메트릭 모델링 기법을 직접 적용해 봄으로써 이 새로운 접근법의 적합성과 효율성을 검토해 보았다.

To date, a smart base isolation system has been developed in high seismicity region such as Japan, USA etc. Smart base isolation systems developed for structures in high seismicity region cannot directly applied to structures in regions of low-to-moderate seismicity such as Korea. Therefore, problems that occur by applying the smart base isolation system developed for the structures in high seismicity region to the structures in regions of low-to-moderate seismicity have been investigated in this study. To this end, a spacial arch structure was used as an example structure and MR dampers and low damping elastomeric bearings were used to compose a smart base isolation system. Artificial earthquakes were used for ground motions in regions of high and low-to-moderate seismicity. Based on numerical simulation results, it has been known that the capacity of smart base isolation system for the regions of low-to-moderate seismicity should be carefully designed because the base isolation effects of the smart base isolation system for high seismicity region is deteriorated when it is applied to the structures in regions of low-to-moderate seismicity.

This paper presents a tuned mass damper (TMD) utilizing a parametric design technique to reduce the dynamic responses to seismic loads of retractable large spatial structures. An artificial intelligence algorithm was developed to automatically search for the installation position of the damping device. This enables confirming the dynamic response of the structure in real time while finding the optimum position for the damping device. Further, the optimum mass of the damping device is determined from among several alternatives, and a design that can be effectively applied to both open and closed conditions of the roof is obtained.

This paper is to draw basic data for the revitalization of the sustainable buildings and the improvement of sustainable building design technology in Korea by analysing the design techniques of sustainable building and the application of the techniques applied to the large volume buildings through the study of foreign cases. This study introduces the design elements of sustainable building applied to the two winter sports stadia and one convention centre which have recently completed for the 2010 Winter Olympics in Canada and analyses the design techniques of sustainable building by the lists of LEED Green Building Rating System as well.
