Computing Simulation

This article provides the numerical elastic buckling analysis of simply supported cold-formed lipped channels subjected to pure bending. A methodology for computing simulation of a new type of thin-walled thermo-profile (reticular-stretched) is developed. For flexural elements buckling modes and values of critical force are calculated. FE simulation evaluates the influence of web height and span on the critical load and buckling modes for cold formed beams of different lengths.

New Generation

Cold formed steel members with edge stiffened holes are a new generation of cold formed members recently developed by the building industry. Very little research has been performed on such sections to determine their local and distortional buckling capacity. This article provides the numerical results of elastic local buckling analysis of cold-formed lipped channels with edge stiffened holes. For flexural elements values of critical buckling moments are calculated and the influence of hole spacing and diameter on elastic buckling capacity is determined.
