Axisymmetric bending solution of shells of revolution by the generalized differential quadrature rule

摘要: A generalized differential quadrature rule (GDQR) proposed recently by the authors is applied here to obtain axisymmetric bending solution of shells revolution, which includes both long and short cylinders storage tanks with stepped wall thickness. The boundary conditions for are simplified in a practical way. analysis tank thickness formulated aid domain decomposition, compatibility expressed explicitly. annular bottom plate shell considered as part whole. engineering design concrete ring discussed considering an accurate assumption interaction between foundation. Examples presented demonstrate efficiency GDQR.
