This paper describes the adaptive roof structure applying VGT (Variable Geometry Truss). In the study from part 5 to 6, the study of the variable structure applied by the cantilever type was done and the large scale movable monument held on Aichi EXPO 2005 was developed. In part 7, the arch structure roof by VGT and its variable motions were examined. In the arch structure, the both edges of the structure are supported at each hinge. It is very difficult to determine the shape of the structure because these tips are absolutely suited at the hinge position. Using inverse analysis method for shape change of arch structure, the structural characteristics in edge conditions were simulated by dynamical FEM methods. In case of fixed edge, the design of VGT mechanism accompanied with arch motions was enabled. In order to develop the movable roof structure, mechanism of outward panel accompanied with structure motion was introduced in detail. As results of these studies, the optimal and rational shape design of the arch structure was concretely produced.
