Abstract

There is the continuation of research of the stress-strain state of a new non-canonical form of thin-shell structure. The study is carried out on a 1:10 scale reinforced concrete model of the "Yasuní" shell with the use of a calculation system based on the Finite Element Analysis of structures (FEA). The mesh of finite elements for the analysis is triangular and has been based on the architectural conception that fuses harmonically in a single structure the characteristic forms of the flora and fauna of the Ecuadorian Amazon. The shell is analyzed with different compression resistance of concrete (f'c = 18.5 MPa, f'c = 22 MPa and f'c = 25.5 MPa) and the thickness varies from t=5 cm to t=10 cm in increments of 1 cm, without edge beams and under the action of self-weight as a uniformly distributed gravitational load. This paper introduces the results of the research of stress-strain state of the scale model of "Yasuní" shell and the authors will continue to study the work of this shell with the modification of various geometric parameters, loads, materials and boundary conditions with the inclusion of edge beams.
