In general, stadium structure with long span has low inherent natural frequency. In the stadium structure, structural behavior similar to resonance can be occurred easily by spectator rhythmical movements of which exciting period is small comparatively. It is required to investigate the safety and the serviceability of stadium structure. Therefore, there exists a necessity for accurate vibration analysis. Accurate analysis of stadium structure subjected to dynamic load is required for economical construction and safe design of stadium structure. Stadium structure should be modeled by refined mesh for accurate vibration analysis. As the mesh of stadium structure is refined, the number of divided elements increases in numerical analysis. The number of node is increased and numerous computer memories or computational time are required. So it is very difficult to analyze refine model of stadium structures by using the commercial programs. It is possible to efficient vibration analysis of stadium structure by finite element modeling method using equivalent beam element proposed in this paper, because the number of nodes is decreased remarkably.

Stadium stand could be led to significant dynamic response due to rhythmical activities of spectator. The dynamic loads induced by spectators movements are considered as static loads in design standard of many countries but these loads have dynamic characteristics. So, it is desirable to apply measured dynamic loads created by spectator activities and to analyze the dynamic behavior of stadium system. The precise investigation of the dynamic loads on stadium structures and the accurate analysis of dynamic behavior of stadium systems are demanded for effective design. As the floor mesh of stadium stand is refined, the number of nodes increase in numerical analysis. So it is difficult to analyze entire stadium structures and much more computer memory are necessary for vibration analysis of stadium system. In this study, the various dynamic loads induced by spectator movements are measured and analyzed. And new modeling method that reduce the nodal points of stadium systems are introduced. Vibration analysis of stadium system is executed to inspect the accuracy and the efficiency of proposed method in this paper.

The cable staying roof structure of Jeju worldcup stadium should be erected with correct prestressed force that is required by the structural engineer who designs this structure. This study evaluated and adapted the erection process of cable, the erection force and the measurement of cable force for Jeju worldcup stadium. The process of erection is required not only to calculate erection force but also to check structural stability, following process, construction period and using cranes. Considering the site conditions and technical problems, this study can attain successfully the erection of cable staying roof structure of Jeju worldcup stadium with allowable errors.

Soongeui complex stadium is a reinforced concrete frame structure composed of columns, slabs and beams. The stadium, however, is also a special structure because it has a tall tower of electronic display board and slabs inside its own structure which is different from the structures that had been demolished using blasting by then. Explosive demolition for the stadium was carried out from the left-hand side of the outfield stand to the right considering 2 rows of columns supporting the stand as a blasting unit. An overturning demolition method was applied to the tower of electronic display board. Water bags that played the role of multipurpose protection were applied to control the dust. As a result, the demolition project of the special structure of Soongeui complex stadium was judged to be a great success.

This paper summarizes the design and construction of the roof canopy structure for the SEOUL 2002 World Cup Main Stadium with a design inspired by Korean traditional beauty emphasizing images of the Pangpae kite. The stadium has also been designed for maximization of its post-World Cup utility to be used on as every basis by the citizens. The stadium canopy is a unique spatial network of truss members with a tensile membrane roof suspended from 16 masts. The canopy covers 40,950 ㎡. which is clad with a pre-stressed tensile membrane of PTFE coated fiberglass fabric and the glass.

This study evaluated and adapted the erection process of cable, the erection force and the measurement of cable force for Jeju worldcup stadium. The process of erection is required not only to calculate election force but also to check structural stability, post process, construction period and using cranes. Considering the site conditions and technical problems, this study can attain successfully the erection of cable stayed roof structure of Jeju worldcup stadium with allowable errors.

This study was conducted to analyze the effect of roof membrane on light environment that influence on turfgrass growth under domed stadium. Roof structure on experimental plot was constructed with PTFE and PE same as Busan Asiad Main Stadium. Tested turfgrass species were combinations of cool-season grasses(Kentucky Bluegrass, perennial ryegrass, $KBG80+PR20\%,\;KBG33+PR33+Fine fescue33\%)$ and warm-season grasses(zoysiagrass, 'An-yang middle-leaf, 'Zenith', Bermudagrass) established with seeding or sodding. The experimental set-up and research work were initiated November 1999 and finished on August 2000 at near Busan Asiad Main Stadium. By the result of computer simulation of daylight radiant energies on the turf surface were lower than needs of normal sport turf growth. The shortage of radiant resulted pest infection on cool-season grass mixture compared with warm-season. But turf color and density showed the best results on Kentucky bluegrass or its mixture plot. Over all the results showed that the best quality of turfgrass growth was occurred on full sun area, and the next was under PTFE membrane. The application of artificial lighting system may increase the turfgrass growth under domed stadium(partially) covered with roof membrane.

Construction of roof structure, cable suspended structure, for Pusan main stadium is adapted a lifting method that is VSL lifting system. 5 processes are practiced for erection of the roof structure including the first lifting process for erection of upper cables and the second lifting process for erection of lower cables. Since all cables of this roof structure with two open spelter sockets are determined their length, some cable were wrong length, he roof structure would be unstable. But, At complete of erection for the roof structure each cable is attained to theoretical tension force with average 4% errors.
