Load-bearing behaviour and structural analysis of slender ring-stiffened cylindrical shells under quasi-static wind load
AbstractThis paper presents the results of physically and geometrically nonlinear analyses of the load-bearing capacity of slender wind-loaded cylindrical shells. These structures do not, even though their geometry is beam-like, behave as beams. The reason for this behaviour deviating from classic beam theory lies in the non-uniform wind pressure along the circumference, which leads to an ovalization of the cross section. There are two global and one local failure modes. The global failure modes are fundamentally different from those of squat shells with h/r<15. The top-stiffened shell in the geometrical transition range of shell-beam does not present the worst case. Additional ring-stiffeners lead to a loss of load baring capacity. Some conclusions are drawn from nonlinear parameter studies for the design practice.
