Probabilistic models for blast parameters and fragility estimates of steel columns subject to blast loads
… column for the limit states of flexure, local buckling and global buckling. As part of the work, we propose four probabilistic blast load models. For different types of explosives and atmospheric conditions, two models predict the incident and reflected peak pressure generated by the explosion …

Refined design expressions for in-plane girder stiffness and system buckling capacity
Lateral-torsional buckling at the system level (global buckling) has been the subject of several research studies over the past 20 years. This buckling mode often controls over conventional lateral-torsional buckling (buckling between braces points) when the girder system is long and narrow. One of …

Elastic buckling solutions for thin-walled metal columns with perforation patterns
… strip methods for use in predicting elastic buckling strength of cold-formed steel columns. These methods were developed by examining elemental behavior of cross-sections in eigen-buckling analyses and validated using a large database of finite element rack-type columns with perforation …

Performance evaluation of spanning systems
… In the second part, dynamic performance and global buckling are investigated to determine their influence on the performance of beams and trusses. These failure mechanisms should be examined early in the design process, but similar types of studies rely only on static behavior to evaluate …

Behaviour of elliptical tube columns filled with self-compacting concrete
… large slenderness ratios were dominated by global buckling. Moreover, the composite columns possessed higher critical axial compressive capacities compared with their hollow section companions due to the composite interaction. However, due to the large slenderness ratio of the test …

Nonlinear inelastic analysis of concrete-filled steel tubular slender beam-columns
… slender beam-columns may undergo local and global buckling when subjected to biaxial loads, preloads or cyclic loading. The local buckling effects of steel tube walls under stress gradients have not been considered in existing numerical models for CFST slender beam-columns. This thesis …

Cold-Formed Steel Behavior: Elastic Buckling Simplified Methods for Structural Members with Edge-Stiffened Holes and Purlin Distortional Buckling Strength Under Gravity Loading
Elastic Buckling Simplified Methods for Structural Members with Edge-Stiffened Holes: Presently, the current design methods available to engineers to predict the strength of cold-formed steel members with edge-stiffened holes remains largely unaddressed in the North American Specification for the …

Effect of Thermal Loading on the Performance of Horizontally Curved I-Girder Bridges
… indicate that uniform thermal loading leads to global and local buckling along the Igirder web centerlines, lateral distortional buckling in the web cross section, and thermal stresses in the I-girder webs. Although pier flexibility is shown to reduce the magnitude of thermally induced local and …

Energy Absorption of Metal-FRP Hybrid Square Tubes
… adding a very thick FRP section may result in a global buckling failure mode (rather than local folding). Until now, there are no studies specifically addressing the effect of FRP thickness on energy absorption of hybrid tubes. In this study, the effects of fiber orientation and FRP thickness …
