Abstract It is hard to imagine architecture and construction without large-span shells of various applications and taking into consideration the requests of architects, the new achievements in numeral modeling of the surfaces and introduction of new groups of tailored surfaces, the appearance of new forms and types of thin-walled shell structures of this kind is inevitable. The bionic method of solving these tasks pushes the boundaries of these opportunities. The subject being studied is the stress strain state of new uncanonical shell “YASUNI”, designed of monolithic reinforced concrete with the use of modern finite element analysis settlement system. The form of the shell is built on the basis of images of the Ecuadorian flora. The form of the shell imitates a leaf of a flower laying on the lay of the land. The triangle finite-element mesh is created with a harmonic fusion of lily and daisy in a single structure. The shell is designed as a solid-cast one, made of different classes of reinforced concrete (В25, В30, В35) with thickness from δ = 5 cm to δ = 10 cm with a step 1 cm without contouring beams. The structure is subjected to self-weight. The article introduces the first results of the research of stress strain state of the shell “YASUNI”. The authors continue the research of the work this shell with different geometrical parameters, the boundary conditions with the addition of contour elements. Due to the computing complex SCAD OFFICE, precision of which is enough to perform calculations it is possible to reach the most advantageous technical-and-economic indexes of the researched uncanonical shell.
