On Critical Buckling Loads of Columns under End Load Dependent on Direction
Most of the phenomena of various fields of applied sciences are nonlinear problems. Recently, various types of analytical approximate solution techniques were introduced and successfully applied to the nonlinear differential equations. One of the aforementioned techniques is the Homotopy analysis method (HAM). In this study, we applied HAM to find critical buckling load of a column under end lo...
متن کاملBuckling of liquid columns.
Under appropriate conditions, a column of viscous liquid falling onto a rigid surface undergoes a buckling instability. Here we show experimentally and theoretically that liquid buckling exhibits a hitherto unsuspected complexity involving three different modes-viscous, gravitational, and inertial-depending on how the viscous forces that resist bending of the column are balanced. We also find t...

متن کاملDetermination of Buckling Loads from Triaxial Load Tests of Slender Concrete-filled Tube Beam-columns
This paper briefly describes efforts at determining buckling loads of slender concrete-filled tube beam-columns. Although utilizing state-of-the-art equipment and controllers, unexpected difficulties were encountered on extracting buckling loads for the specimens due to (a) frictional forces in the actuators, (b) large initial bidirectional imperfections, (c) initial stresses due to constructio...
متن کاملEuler Buckling of Thin - Walled Composite Columns •
Pultruded composite structural members with open or closed thin-walled sections are being extensively used as columns for structural applications l1Jhere buckling is the main consideration in the design. In this paper, global buckling is investigated and critical loads are experimentally determined for various fiber reinforced composite I-beams of long column length. Southwell's method is used ...
