The invention relates to a structure assembled from elements, the elements forming an entity with topological interlocking. To improve structures of this type, the invention proposes a self-supporting structure comprising hollow, tublar element (), which are put together with parallel axes to form an interlocking entity without any binder as a composite layer, in which the element (), respectively lying only loosely against one another with linear contact, are held together by a frame () or the like extending around the element structure and determining the flexural elesticity of the structure by its own restraining force, each of the elements () having a circular middle cross section () starting from the circumference of which the generated convex half-surfaces of the element (), go over in a smoothly curved manner to the two element ends, the edge contour () of which repectively has the form of a flat ellipse having pointed major-axis vertices (), the major axes () of which, lying normal to the longitudinal axis () of the element, are turned bywith respect to each other about the longitudinal axis () of the element, the axial ratio of the two ellipse axes () in a cross section lying normal to the longitudinal axis () of the element increasing continuously from the center of the element () respectively to its ends.
