Abstract

The concrete ffshore platforms, which are subjected a several loading combinations and, thus, requires an analysis more generic possible, can be designed using the concepts adopted to shell elements, but the resistance must be verify in particular cross- sections to shear forces. This work about design of shell elements will be make using the three-layer shell theory. The elements are subject to combined loading of membrane and plate, totalizing eight components of internal forces, which are three membrane forces, three moments (two out-of-plane bending moments and one in-plane,or torsion, moment) and two shear forces. The design method adopted, utilizing the iterative process proposed by Lourenço & Figueiras (1993) obtained from equations of equilibrium developed by Gupta (1896), will be compared to results of experimentally tested shell elements found in the literature using the program DIANA.
