Simulation of Cold-Formed Steel Beams in Global and Distortional Buckling

Abstract

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.

Laboratory studies of the dynamic properties of soils of weak bases using the Fourier method

“…Cyclic triaxial test conducted by the test of continuous cylindrical soil samples at their full loading them pressure (isotropic compression) by applying axial and cyclic load capabilities without drainage. [2,5,6] Test work are carried out in three stages: water saturation, consolidation and cyclic loading. After the samples are completely water saturated, in the second stage, they undergo isotropic or anisotropic consolidation.…”

“…It has a number of properties that are convenient to use in solving dynamic problems and for describing seismic effects. Fourier spectra are widely used in engineering seismology and serve as the main means of assessing the spectral composition of recorded ground movement or structure reactions [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

Applicability of thin-walled structures for energy-savings in steel construction

“…CFS are structures manufactured from cold-rolled sheet steel (0.6 ÷ 3 mm) by cold bending on rolling mills with subsequent galvanizing [8][9][10][15][16][17][18][19]. They are an effective alternative to traditional hot-rolled profiles in the case when the use of the latter is irrational.…”

Complex Testing of the Bridges

“…The columns are calculated as a couple, with the existing crosssection of MB 30. From the interactional curve above, it is clear that the performed reinforcement raised load capacity with very small changes in geometry as in width, and height [39][40][41][42].…”
