In this paper, the new version of differential quadrature method (DQM), for calculation of the buckling coefficient of rectangular plates is considered. At first the differential equations governing plates have been calculated. Later based on the new version of differential quadrature method, the existing derivatives in equation are converted to the amounts of function in the grid points inside...

At the moment, Moshanir loading code which has been provided by Tavanir Company in 1998 is used for loading transmission line towers. Also ASCE52 are applied for designing these structures. In the above Moshanir loading code, loading parameters such as, maximum yearly ice thickness, maximum monthly ice thickness, maximum yearly wind speed and maximum monthly wind speed have been considered as ...

Analytical solutions for elastic buckling and post-buckling geometries are scarce. The present work presents such a solution sample geometry, initially planar, which buckles into complex 3D shape under tensile load. assumptions that the thickness is small, so flexural stiffness low compared to in-plane strain stiffness, hence can be considered inextensible. initial geometry composed of two disk...

In this contribution, a previously introduced discrete model for studying the statics of duoskelion beam-like structures is extended to dynamics. The results numerical simulations performed using such an are reported discuss in-plane dynamic buckling under different loading and kinematic boundary conditions. core instrument analysis beam element, which, in addition flexure, also accounts extens...

In this study, buckling analysis of panel types of marine and offshore structural components with initial imperfection under the combined action of lateral pressure and axial compression is carried out. The governing differential equations for thin and moderately thick shells are developed in terms of components of the displacement field. The governing ordinary differential equations are then d...
