| Summary: | The paper presents a formulation of degenerate shell finite elements which take into account three-dimensional states of stress and strain throughout the element. The formulation was developed with the aim of modelling reinforced concrete shell structures subjected to high transverse shear stresses. It requires implementation of a three-dimensional constitutive model for concrete and it allows to use out-of-plane reinforcement in the elements. Through the consideration of three-dimensional stress states, the elements can model the influence of in-plane stresses on transverse shear deformations and the influence of transverse shear stresses on the capacity of shell structures. The formulation was verified against experimental results. The specimens analyzed were shell panels subjected to out-of-plane (transverse) and in-plane shear and reinforced concrete shells subjected to punching shear. |
