Influence of Local Buckling on Loaded Capability of Plates with Complex Configuration

UDK: 624.154.5

П.А. Косых, Г.Г. Кашеварова

The article focuses on the approach of defining plates loaded capability of the complex configuration through profile “ATLANT” web. The main points of creating the design model are described, including the finite element type choice, the determine boundary conditions, defining material characteristics, etc. Special attention is given to buckling modes and the value of initial geometric imperfections. Calculating principles of the full “unreduced” cross sectional area are presented. The comparative analysis with the results of identified stresses which define bearing capability exhausting was done. The series of calculations of various configurations of the web under study are done. The principles of obtained results unification are considered with the aim of approximating curve fitting. Eventually the required relation connecting actual load with maximum stresses is defined. All calculations were done by means of finite-element software ANSYS.
