A numerical shape finding procedure for very thin shells (Q1905591)

The paper introduces a numerical shape-finding procedure for very thin continuous shells: an assigned loading distribution is applied on a point-wise suspended membrane, which, after its deformation, is inverted to give the geometry of a reinforced concrete continuous shell. The geometrically nonlinear analysis of the membrane is carried out taking into account large displacements and finite rotations. Finally, the structural analysis of the shell, including stability aspects, is performed to check and control the membranal-like behaviour of the structure.
