Abstract: In this paper, the shells limited by two flat concentric circles are considered.Both families of coordinate lines are sinusoids. Their middle surfaces may be associated to the group of velaroidal type surfaces. Considered surfaces can find application in landscape architecture and also in design of some manufactured details and structures as consist of cyclically repeating identical elements.The stress-strain state of ashell outlined on the considered surface and loaded by the dead weight is defined.
Keywords: A velaroidal surface, a thin-walled shell, architecture, the stress-strain state.
