Stability of wind-loaded cylindrical shells
AbstractStability analysis of perfect and imperfect cylindrical shells under wind pressures is performed using the finite element method. A 48 degree-of-freedom (d.o.f.) thin shell element previously developed by the present authors is used. The element is free from both shear and membrane locking and is capable of modelling shells with arbitrary imperfections. Nonlinear effects due to prebuckling rotations are taken into account. The nonlinear response is obtained using Riks-Wempner algorithm. Effects of the imperfection amplitude and that of the material orthotropy on the limit load points are studied. Wherever possible, the present results are compared with existing results. A favorable agreement is observed.
