Abstract

The aim of the paper is to analyse the effectiveness of FRP reinforcement of steel torispherical shells. The failure modes of unreinforced and reinforced torispheres are studied, taking into account the various geometrical and mechanical properties of the shells and reinforced layers. Both local and full reinforcement are considered as well as perfect and imperfect shells. The influence of fibre orientation on the limit pressure is also investigated in order to find the optimal stacking sequence. The theoretical analysis is verified by various experimental tests. However, the tests were limited to just one geometry of steel torisphere, i.e. t s/R = 0·01, R/D = 0·6 and r/D = 0·24.
