Note (General): In this paper, the structural concept of adaptive planar trass structures is evaluated from the viewpoints of both geometrical adaptivity and dynamic characteristics, and an attempt is made to clarify the basic idea concerning what kind of adaptive planar truss structures are desirable to realize the concept in real structure hardware. The basic octet elements for planar truss structures and their various modified configurations, including cube elements, are arranged for the idea of adaptive elements. Two ways of obtaining an appropriate curved surface from a flat truss structure, that is, the bending concept and the shear concept, are related to the adaptive elements. Stiffness properties of some basic adaptive planar truss structures, which consist of cube elements, in a comparatively moderate or small scale are investigated through vibration analysis using FEM. Vibration characteristics for various configurations, such as flat, parabolic cylinder, elliptic paraboroid and hyperbolic paraboloide are shown.
