This paper aims to discussion the characteristics of location and spatial organization on the Donam SeoWon(confucian academy). To do this, we studied in analysis of the present conditions and photographing, research materials about the from of physical structure and review of historical documents. The result of analysis in the sight of the location and spatial organization was good matched. The spatial organization of the Donam SeoWon(confucian academy) was divided into entry space, lecturing space, management space and sacrificial space. Jonhakhumyo constructs axis of “Sanangru - Ipdeokmun - Yangseongdang - Naesammun - Sungryesa” and Eungdodang that not removed hall with 1880 shows characteristics a right angle in the left side of axis remove to location of present 1971. The result of this study, analysis of axis and Spatial structure shows backgrounds of these locations shows that the political and social, economical phenomena were influenced to the locations and spatial organization of the Donam SeoWon(confucian academy).

In this study we analyze categorical data by means of spatial statistics and echelon analysis. To do this, we first determine the hierarchical structure of a given contingency table by using echelon dendrogram then, we detect candidates of hotspots given as the top echelon in the dendrogram. Next, we evaluate spatial scan statistics for the zones of significantly high or low rates based on the likelihood ratio. Finally, we detect hotspots of any size and shape based on spatial scan statistics.

The objective of this research is to development of a parametric design system for membrane structures. The parametric design platform for the spatial structures has been designed and implemented. Rhino3D is used as a 3D graphic kernel and Grasshopper is introduced as a parametric modeling engine. Modeling components such as structural members, loading conditions, and support conditions are developed for structural modeling of the spatial structures. The interface module with commercial structural analysis programs is implemented. An iterative generation algorithm for design alternatives is a part of the design platform. This paper also proposes a design approach for the parametric design of Spoke Wheel membrane structures. A parametric modeling component is designed and implemented. SOFiSTik is examined to interact with the design platform as the structural analysis module. The application of the developed interface is to design optimally Spoke Wheel Shaped Ductile Membrane Structure using parametric design. It is possible to obtain objective shape by controlling the parameter using a parametric modeling designed for shape finding of spoke wheel shaped ductile membrane structure. Recently, looking at the present Construction Trends, It has increased the demand of the large spatial structure. But, It requires a lot of time for Modeling design and the Structural analysis. Finally an optimization process for membrane structures is proposed.

본 연구의 목적은 지속 가능한 도시성장 관리를 위한 일환으로 도시균형발전을 위해 공간모델링 기법을 이용하여 도시공간 구조 진단하는 것이다. 도시공간구조는 다양한 활동의 상호작용이므로 공간구조 요소들의 패턴 변화 분석과 함께 요소들의 분석 결과를 연계하여 살펴볼 필요가 있다. 이를 위해 본 연구에서는 인구, 교통 분야에 대하여 접근하였으며, 대상지의 관련 법령에 따라 정의된 다양한 생활권별 공간구조를 분석하였다. 인구는 시계열별 변화 데이터를 공간통계기법인 Getis-Ord G_i^* 기법에 적용함으로써 인구 집중지역에 대한 군집 변화를 분석하였으며, 교통은 출퇴근 교통 O-D 데이터를 Social Network Analysis 기법에 적용함으로써 중심성 변화를 분석하였다. 분석결과 대상지 전체적으로 불균형이 심화되고 있었으며, 중심성의 변화가 분석되었다. 분석 결과는 다른 공간요인과 연계하여 해석함으로써 생활권별 도시공간구조를 전망하고 지속 가능한 도시성장관리를 위한 방향을 제시할 수 있었다. 이러한 결과는 해당 도시에서 진행되고 있는 도시정책뿐만 아니라, 전 세계 많은 도시에서도 급속한 도시발전과 통제할 수 없는 개발에 대응하기 위하여 도입하고 있는 다양한 도시 성장 관리 정책의 의사결정을 위한 도구로 활용할 수 있을 것이다.

Landscape structure is important to understand a complex patterns and interaction with adjacent habitat in rural area. The aim of this study is to analyze relationship between landscape structure and insect spatial distribution in rural area to suggest applicable possibility of landscape structure as biological indicator. For this purpose, first, four landscape structure criteria such as distance from the forest; density of farmland-forest ecotone; landscape continuity; and field size are selected. Secondly, these criteria are applied to Gangsang-myeon, Yangpyeong-gun where mosaic feature are conserved at various spatial scale. Thirdly, application of landscape structure criteria is verified using correlation with species number, species diversity, and species richness of insect. As a result, it could be suggested that the landscape structure criteria are useful for explaining insect spatial distribution.

The Zhuhai Opera House has an external structure consisting of a type of spatial steel, where the stress of steel elements varies with the ambient temperature. A structural health monitoring system was implemented at Zhuhai Opera House, and the temperatures and stresses of the structures were monitored in real time. The relationship between the stress distribution and temperature variations was analysed by measuring the temperature and stresses of the steel elements. In addition to measurements of the structure stresses and temperatures, further simulation analysis was carried out to provide the detailed relationship between the stress distributions and temperature variations. The limited temperature measurements were used to simulate the structure temperature distribution, and the stress distributions of all steel elements of the structure were analysed by building a finite element model of the Zhuhai Opera House spatial steel structure. This study aims to reveal the stress distributions of steel elements in a real-world project based on temperature variations, and to supply a basic database for the optimal construction time of a spatial steel structure. This will not only provide convenient, rapid and safe early warnings and decision-making for the spatial steel structure construction and operation processes, but also improve the structural safety and construction accuracy of steel space structures.

Spatial Structure has suffered from a lot of damage due to the use of lightweight roofs. Among them, the damage caused by strong winds was the greatest, and the failure of the calculation of the wind load was the most frequent cause. It provides that wind tunnel test is used to calculate the wind load. However, it is often the case that the wind load is calculated based on the standard of wind load in the development design stage. Therefore based on this, the structure type and structural system and member design are often determined. Spatial structure is usually open at a certain area. The retractable roof structure should be operated with the open roof in some cases, so the wind load for the open shape should be considered, but it is not clear on the basis of the wind load standard. In this paper, the design wind pressure of a closed and retractable roof structure is calculated by KBC2016, AIJ2004, ASCE7-10, EN2005, and the applicability of wind pressure coefficient is compared with wind tunnel test.

In this study, the seismic performance and behavior characteristics of the upper truss structure of the large stadium are analyzed by nonlinear dynamic analysis. In the nonlinear dynamic analysis, the earthquake records were generated by site response analysis to simulate the nonlinear behavior of the relevant soil condition where the structure is located. Nonlinear dynamic analysis was performed using Perform-3D and the nonlinear properties of the substructure and the superstructure were determined in accordance with KISTEC guideline. According to the analysis results, excessive deformation occurred in the upper truss element, and plastic hinges exceeded the target performance in some members. Buckling-restrained brace is used for seismic retrofit of stadium structures and the analysis results shows the interstory drift satisfies the target performance level with dissipating the seismic energy efficiently.

The purpose of this study is to validate the validity of the methodology for analyzing the space with complex characteristics and to evaluate the existing spatial structure analysis theory. Seven example models are designed and analyzed data of spatial syntax analysis and visibility graph analysis. And analyzed the agent-based model using two analytical methods: the adjacent space and the whole spatial connection. The results of this study are as follows. Based on the analysis of the agent - based model for perfectly freewalking, the validity of the method is verified in terms of predictive ability and effectiveness. Agent-based models can be simulated considering various variables, so realistic predictions will be possible and a new biography of complex systems can be met.
