In this paper, always monitoring system of fiber Bragg Crating(FBG)Sensor is described and FBGs are well suited for measuring the movement in the part of the spatial structure(for example, cable, membrane and so on)under the pressure conditions. In order to measure the movement of long span structure, we need the measurable equipment that takes in many spots to measure. In the result of experiment, the fiber sensors showed good response to the pressure conditions. Therefore, We could calculate the movement of spatial structure and be possible health monitoring of the spatial structure.

달걀낙하시험시 사용되었던 안정한 형태에서 아이디어를 얻어 구조물의 형상을 결정하게 되었다. 사이트의 가장 큰 특징인 수변공간을 유지하는 동시에 활용하는 방안으로 띄운 구조를 적용하였다. 리조트 시설인 공간의 특성에 따라 대공간구조를 사용하여 긴 스팬을 최대한 이용하는 반면 지반에 전달되는 연직하중을 최소한으로 하고자 하였다. 이 구조물은 서울이라는 거대한 도심의 중심에 위치하는 휴식공간인 동시에 랜드마크가 될 것이다.

Spatial structures is a appropriate shape that resists external force with only inplane force by reducing the influence of bending moment, and it maximizes the effect of structure system. An economic analysis is one of the most important factors to determine the project feasibility. Large spatial structures project is more need to comprehensive technology than a general construction project. In order to result in success of these project, it is desired that analyze an essential elements(for example, large budget, professional engineer, construction method, etc.) in the whole life cycle of buildings by schematic preparation from the early feasible study steps. We collect the data and analyze construction cost through this study which examines general remarks of existing spatial structures and researches its examples. This study is aimed to apply basic data to establish database the spatial structures.

It is important to design the optimal shape in the initial process because the influences on the design and construction are large according to the shape and pattern of spatial structures. However, the existing optimal shape designs for spatial structure are performed by the designer's intuition and experiences. Therefore, this study proposes the integrated process using the topology optimization and cellular automata model. First, the initial optimal shapes are obtained by using the topology optimization, and then the spatial truss structural patterns are created through the application of cellular automata rules. Finally, the optimal shapes to satisfy the various design conditions are generated by the structural analysis and size optimization.

대공간구조물의 계획을 위하여 장스팬 구조물의 계획을 실시하였다. 보나 슬래브 부재는 상부에 압축력과 하부에 인장력을 받는다. 일반구조체로 120M 의 장스팬을 감당할 수 없으므로 케이블의 인장력을 이용한 대공간구조물을 계획하였다.

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.

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.

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.

An economic analysis is one of the most important factor to determine tile project feasibility. In some mega project, however, it is not unique factor to make a Go or No-Go decision because of overriding this work, an economic aspect by some project indirect factor such as political, social, environmental and technical factor, etc. The purpose of the this study is to investigate the cost model effects of spatial structure.
