Retractable roof system is one of the special feature in stadium or complex structure. And this retractable roof system makes possible to use spacial structure all-weather. This retractable roof system is able to classified into overlapping, parallel movement and folding system. Moving load, impact load, inertial or braking loads, these dynamic loads induced by movements of retractable roof system. So it is necessary to analysis of spacial structures are subjected to these dynamic loads. Dynamic loads that are induced by the retractable roof movements can be applied to moving mass method or moving force method. But, moving force method is appropriate because the retractable roof movements is slow relatively. In this paper, new application method of moving forces induced by the retractable roof movements is proposed. And vibration analysis of spacial structures are executed by using the proposed method. This proposed equivalent moving force can be easily applied to spacial structure that is subjected to dynamic loads induced by movement of the retractable roof system.

The purpose of this study is to investigate the change of spacial structure from rural space to urban space and to examine the characteristic of spacial restructure, focusing on the Hwamyeong-Dong of Buk-gu in Busan. Hwamyeong-Dong has changed from rural area to urban area because of spacial expansion owing to industrialization and urbanization. The unique natural environment, rural village, etc. were disappeared and instead the apartment complex, commercial building, and so on were built. For this reason, historic and concrete place were vanished and so the spacial homogenization and uniformization were formed centering around apartment complex. But the singularity of Hwamyeong-Dong exposes in the way that unique history, custom and memory, trace of Hwamyeong-Dong preserved through the support and effort of the residents and that the Daechen stream changed to ecological stream. In addition, Hwamyeong-Dong altered heterogeneous, multi-layered urban space from homogeneous rural space in terms of the apartment supply sectors and scale, the distribution and kind of commercial facility, residents's composition. This has brought about the subdivision, hierarchization of the space as well as the residence, education, culture. Especially, Hwamyeong3-Dong that built to large scale apartment complex are significantly different from Hwamyeong2-Dong. Hwamyeong2-Dong is marginalizing step by step. However, It is found that the residents in Hwamyeong2-Dong are making an effort for liveable place with ecological residential community and educational cultural community as the center.

The seismic isolation systems could be used to reduce the seismic response of a structure. The natural period of a structure with seismic isolation system got be long to avoid the prominent seismic period. The purpose of this study is to analyzed the seismic behavior of the truss arch that is supported to column with LRB. Truss arch structures subjected to horizontal seismic have large horizontal and vertical response unlike seismic behavior of normal rahmen structures. When seismic load is applied to the truss arch with isolation systems, the horizontal acceleration response of the truss arch is reduced and the vertical seismic response is remarkably reduced. Also, the seismic behaviors of the truss arch with strengthen column as like lattice column are very similar to that of the truss arch supported to directly foundation. The Seismic Isolation system can be applied to reduce efficiently the seismic response of the spacial structure with not strong column.

In large commercial facilities, customer movements have a close interrelation between space structure and interior environment elements. With the importance of the spacial structure, VMD strategy has recently played greater role In the interior environment image to satisfy customers' needs. This study intends to examine the relationship among customer behavior, customer movement, and VMD by grasping customers shopping behavior characteristics that come from the relatively comprehensive factors in the female sections of the department stores through the environmental image that is composed of spatial and emotional elements. This study also serves the purpose that by tracking shopping time, shopping speed, and the ratio of shopping depth that directly reflects customer behavior characteristics, various causes, either general or specific, which can affect the decision on purchase are to be examined. Based on this research results, we bring up the basic data and foundation for floor MD plan, establishment of movement plan, and VMD plan at a store.

Auditorium and gymnasium are utilized in rare cases compared to the large spacial size. From Monday to Saturday, the use of them is extremely rare, which shows the serious example of economical inefficiency of architectural space. To solve these problems, inquiries from the various viewpoints will be necessary. Architecture-philosophically, how can space and time considered sufficiently? How is the structure related to phase. The object of this study is to arrange newly economical efficiency of space and time which are treated slightingly as they mentioned above and the plan about the design of the architectural space and multipurpose room.

Many researcher's efforts have made a significant advancement of space frame structure with various portion, and it becomes the most outsanding one of space structures. However, with the characteristics of thin and long term of spacing, the unstable behavior of space structure is shown by initial imperfection, erection procedure or joint, especially space frame structure represents more. This kind of unstable problem could not be set up clearly and there is a huge difference between theory and experiment. Moreover, the discrete structure such as space frame has more complex solution, this it is not easy to derive the formulation of design about space structure. In this space frame structure, the character of rise-span ratio or load mode is represented by the instability of space frame structure with initial imperfection, and snap-through or bifurcation might be the main phenomenon. Therefore, in this study, space frame structure which has a lot of aesthetic effect and profitable for large space covering single layer is dealt. And because that the unstable behavior due to variation of inner force resistance in the elastic range is very important collapse mechanism, I would like to investigate unstable character as a nonlinear behavior with a geometric nonlinear. In order to study the instability. I derive tangent stiffness matrix using finite element method and with displacement incremental method perform nonlinear analysis of unit space structure, star dome and 3-ring star dome considering rise-span $ratio(\mu}$ and load $ratio(R_L)$ for analyzing unstable phenomenon.

Due to the traffic congestion of the city and public transportation-oriented policies in large cities, public transportation is receiving attention and being used increasingly. However, relatively less research on the design and distribution of public transportation network and limitations in quantitative approaches have made implementation and operation practically difficult. Over- or under-supply of transportation routes caused unbalanced connectivity among areas and, thus, differences in time, expenses and metal burden of users traveling the same distances. On the other hand, the Space Syntax theory, originally designed to calculate the connectivity of urban or architectural spaces, helps generate quantitative connectivity of whole space simply based on the spacial structure. This study modified the original Space Syntax algorithm to fit the public transportation problem and showed how it is applied to a transportation network by creating an artificial GIS network.

Trade areas of the commercial centers in Chongiu City are rapidly changing as the urban spacial structure is transformed, consumer behaviors are changed and large shopping stores are located in the area. The City's CBD has been in the Sung-an-gil district. The trade areas of the CBD have expanded along the major roads in the directions of north, south and west from the Sang-dang park. Especially, two newly formed secondary commercial centers are noticeable: one is the center around the express bus terminal in Gagyong-dong, and the other is formed in the Yongam, Bunpyong and Sannam district. As such changes are intensified, small retailers in the traditional markets that are mainly concentrated in the Yukgerri market place have faced hardship in business and management. The commercial hardship has been hastened up by openings of large discount stores and expanding tendency of internet shopping businesses. Acknowledging the changes in the business environment of traditional markets, this paper attempts to suggest policies to gentrificate the declining market areas in the CBD. The suggested polices are differentiated according to the types of traditional markets, stores. and merchants. And also suggestion is provided regarding amendments of the City's codes.

Recently, the changes of industrial location can be explained as the concentration of small and medium manufacturing firms or high technology industries by industrial restructuring in Seoul metropolitan area, and the dispersion of large companies'branch plant into the peripheral region in Korea. Particularly deindustrialization is progressing in the inner city and manufacturing firms disperse into the outer city in Seoul metropolitan area. This study reviews on the structural perspectives for the changing industrial location factors. The development of capitalism organizes economic spacial structures and Its characteristics can be reasons which can raise changes in industrial location. Korean economy rapidly grew in the movement process of international capital. And capital accumulation by continuous economic growth is raising the spatial division of labor or the spatial difference and inequality on land price, wages. the base of labor reproduction. Therefore, these factors are the most reasons to raise the changes of industrial location in Korea. Hereafter the study on these factors, that is, in relation to sociocultural structure and land use structure have to be progress more concretely.
