Abstract: In the study of the state of deformation stress of multilayer doubly curved shell roof, the boundary conditions have a great effect. However, in the multilayer doubly curved shell roof, the change of each shell thickness also affects the deformation stress in the shell and the appearance of the cracks on the concrete shell is also different. In analytical studies, Vlasov, Ambarsumian, Thanh Huan Le, etc. have been implemented, but it is not clear that how the deformation stress in the shell is if having the effect of the change of each shell thickness. Therefore, in this paper, the author studies the change of the thickness of each shell to consider the effect of such change on the deformation stress in the shell and the phase of appearing the cracks in the concrete in the case the steel fiber concrete layer under the normal concrete layer with the boundary condition that the curved beam section is not changed by ANSYS numerical simulation software.
