Analysis on Calculated Length for Buckling Stability of Steel Pipe Pile Based on Energy Method

Abstract: According to the Winkler assumption, the form of the pile constraint could be simplified as bottom fixing and top free. Considering the influence from resistance of soil around pile, the equations on calculated length for buckling stability of steel pipe pile when the portions along the pile length were constrained in the uniform foundation and the layered foundation were respectively...

Advanced Analysis of Steel Frame Structures Subjected to Lateral Torsional Buckling Effects

Lateral Torsional Buckling of Steel Thin-Walled Beams with Lateral Restraints

Metal thin-walled members have been widely used in building industry. Usually they are utilized as purlins, girts or ceiling beams. Due to slenderness of thin-walled cross-sections these structural members are prone to stability problems (e.g. flexural buckling, lateral torsional buckling). If buckling is not constructionally prevented their resistance is limited by buckling strength. In practi...

DEVELOPMENT OF NEURAL NETWORK MODELS TO ESTIMATE LATERAL-DISTORTIONAL BUCKLING RESISTANCE OF CELLULAR STEEL BEAMS

The lateral-torsional buckling (LTB) strength of cellular steel girders that were subjected to web distortion was rarely examined. Since no formulation has been presented for predicting the capacity of such beams, in the current paper an extensive numerical investigation containing 660 specimens was modeled using finite element analysis (FEA) to consider the ultimate lateral-distortional buckli...

Lateral-torsional buckling resistance of cold-formed high strength steel rectangular hollow beams

Hollow sections have been widely used for steel structures. Applications of High Strength Steel (HSS) on cold-formed hollow sections lead to thinner and lighter structures. This paper presents numerical investigations on the lateral-torsional buckling resistance of the cold-formed high strength steel rectangular hollow beam. Results from finite element analysis using Abaqus software are compare...
