Elastic Initial and Post-local Buckling of Profiled through Girders

Authors

Abstract:

An experiment investigating the elastic local buckling response of trough girders composed of thin profiled steel sheeting has been undertaken Beam tests were performed to promote initial local buckling in a region of constant moment in the elastic range of structural response. The results of the experiments were compared with an elastic complex semi-analytical finite strip method of analysis, and acceptable correlation was obtained. The post-local buckling behavior was monitored in the experiments, and this response showed good agreement with a nonlinear finite strip method developed elsewhere.

Thermal buckling and post-buckling of FGM Timoshenko beams on nonlinear elastic foundation

Buckling and post-buckling thermomechanical deformations of a functionally graded material (FGM) Timoshenko beam resting on a two-parameter nonlinear elastic foundation and subjected to only a temperature rise have been numerically investigated with the shooting method. The material properties are assumed to vary only in the thickness direction according to a power law function. Through-the-thi...

Elastic buckling finite strip analysis of the AISC sections database and proposed local plate buckling coefficients

The objective of this paper is to provide analytical expressions for the elastic cross-section local buckling stress, including element interaction, of hot-rolled steel structural shapes. The crosssection local buckling stress is determined by finite strip analysis. Local stability of each crosssection is considered in axial compression, as well as positive and negative bending about the major ...

Influence of Local Buckling on Global Instability: Simplified, Large Deformation, Post-buckling Analyses of Plane Trusses

Abstract-In this paper, the influences of local (individual member) buckling and minor variations in member properties on the global response of truss-type structures are studied. A simple and effective way of forming the tangent stiffness matrix of the structure and a modified arc length method are devised to trace the nonlinear response of the structure beyond limit points, etc. Several examp...

Post laparoscopic pain control using local anesthesia through laparoscopic ports

Introduction: Although patients do not experience sever pain after laparoscopic surgery, most of them experience acute or chronic pain afterward. While conventional pain killers including NSAID and narcotics in laparoscopic surgery have specific side effects, their application is inevitable. This study compares the efficacy of local anesthetic drugs and conventional pain killers in post-operati...

Elastic Properties and Buckling of Silicon Nanowires

Silicon is the most important material for the electronics industry. Its unique electronic, optoelectronic, thermal, and mechanical properties have made Si an ideal choice for integrated circuits, memory devices, solar cells, and microelectromechanical systems (MEMS). Considering onedimensional (1D) nanomaterials, carbon nanotubes, silicon nanowires, and ZnO nanowires/nanobelts are the three pr...

Modeling Elastic and Inelastic, Critical- and Post-buckling Behavior of Bracing Members

An efficient beam element, the modified elastofiber (MEF) element, has been developed to capture the overall features of the elastic and inelastic response of slender columns and braces under axial cyclic loading without unduly heavy discretization. It consists of three fiber segments, two at the member ends and one at mid-span, with two elastic segments sandwiched in between. The segments are ...
