A parametric study was carried out in order to investigate the buckling capacity of the vertically stiffened cylindrical shells. To this end ANSYS software was used. Cylindrical steel shells with different yield stresses, diameter-to-thickness ratios (D/t) and number of stiffeners were modeled and their buckling capacities were calculated by displacement control nonlinear static analysis.  Radi...

In this paper, the characterisation of elastic shear buckling behaviour simply supported plates diagonally stiffened excluding influence direct stresses is made. Two broad numerical parametric studies consisting linear analysis by finite element method are performed, covering entire practical range critical parameters like aspect ratio and stiffener’s mechanical properties. first study, attenti...

In this paper, bending analysis of concentric and eccentric beam stiffened square and rectangular plate using the meshless collocation method has been investigated. For detecting the governing equations of plate and beams, Mindlin plate theory and Timoshenko beam theory have been used, respectively, with the stiffness matrices of the plate and the beams obtained separately. The stiffness matric...

Ring-stiffened flat bottom tanks are widely used in many industries for the storage of liquids, such as oil, fertilizers, water, sewage and sludge. Material efficiency is achieved by combining thin plates with ring-stiffeners. When bin covered a dome or cone roof, high meridional forces due to live snow loads may trigger axial buckling shell. Ring stiffeners beneficial, not just against wind, b...

This paper studies the efficiency of subgrade stiffening next to the track as a mitigation measure for railway induced vibrations by means of a two-and-a-halfdimensional coupled finite element – boundary element methodology. The pyhsical mechanism is interpreted in the frequency–wavenumber domain, illustrating that the stiffened block of soil next to the track can act as a wave impeding barrier...
