Abstract

This paper describes a movable arch roof with external panels as an actual design of an adaptive structure using a VGT (Variable Geometry Truss) mechanism comprising an elementary truss structure with extendable members. This movable arch structure comprises several VGT units jointed in series and pin jointed at each end. It is a stable structure because its edge is restrained, but this reduces its variety of shape change. Various arch shapes can be determined by using inverse analysis to solve the structure shape from the member lengths. An actual movable roof pavilion composed of such a movable arch and an external panel was designed, and the behaviors of a movable roof and the joint mechanism of the roof elements were verified by numerical simulation and a model experiment. As a result, the performance of the proposed movable roof structure was confirmed, and the basic technology and design approach were established.
