Stress-strain in multi-layer reinforced concrete doubly curved shell roof

Abstract

This paper presents a result of stress-strain in double-layer reinforced concrete doubly curved shell roof by experimental method and simulated by ANSYS. In the analytical method of multi-layer shell by the authors as Ambarsumian, Huan T. Le…with assuming that the layers in shell are stick together, work together, in addition to the analytical solution, there are also limitations in the choice of approximation functions as: the stress function φ and the displacement function w, selection of boundary conditions of the shell…The study of double-layer reinforced concrete shell roof by experimental method and ANSYS show the real work of the shell, as well as the real work of the double-layer shell with the use of normal concrete layer and steel fiber concrete layer in shell, experimental method and ANSYS in the reinforced concrete shell roof model with a square size is 300×300cm.
