The biomimetics has been applied in many fields while its application in structural engineering has not been fully promoted. The applicability of bi-valve shells to spatial structures have been investigated, however, the usefulness of bi-valve shell is not revealed. This is because the mechanical and geometric properties of bi-valve shells are not understood due to its complex shape. In this study, a novel method for measuring mechanical and geometric properties of real shaped bi-valve shell by using X-ray CT images is proposed. Thickness and curvature, and stress evaluation on dead load analyzed using the model created by CT images.
