Experimental Buckling Loads of Water‐Loaded Beams

Journal of Structural Engineering, 1986
This note reports results of two tests performed on full-scale thin-walled prestressed concrete beams where the increase in external load is caused by changing the water level contained in the beam section. The purpose of the experiments was to contrast experimental values of the buckling load with predictions based on a numerical model of the problem,

Buckling of Viscoelastic Columns. Part I: Constant Load Buckling

Rubber Chemistry and Technology, 1985
Abstract The constant load buckling of viscoelastic columns has been studied extensively in the past and equations have been derived to predict the buckling time from the geometry of the columns and the constitutive equation of the material. These theories restrict themselves to columns loaded with an axial load only.

Buckling load for nonuniform columns

Computers & Structures, 1977
Abstract A method to determine an approximate lower bound buckling load for a nonuniform column is presented. The method is applicable to both hinged-hinged and cantilever columns. A finite difference scheme is used to represent the equilibrium equation for the column.

Buckling of Shear Loading Plates with Strengthenings

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000
AbstractThe paper treats the influence of either weakening or strengthening of rectangular plates on the critical external buckling load. The plate geometry was chosen so that the buckling process takes place in the elastic range. The simply supported plate is loaded with shear forces per unit length which act on its edges.

Bounding of Frame Buckling Loads

Journal of the Structural Division, 1970
Frame stability calculations are recast into the form of a low order, nonlinear eigenvlaue problem. It is shown that at each stage of the iterative solution of the problem, upper and lower bounds on the sway buckling load are established. The conditions needed for convergence and bounding are examined and verified by several numerical problems.

Secondary Buckling of Compression-Loaded Composite Plates

AIAA Journal, 1996
The phenomenon is described of secondary buckling in plates that are clamped along the loaded edges and simply supported and stiffened along the adjacent unloaded edges. An experiment is described that is used to study secondary buckling of plates with these boundary conditions.

Extrapolation Techniques for Buckling Loads

Journal of Structural Engineering, 1983
The southwell, modified and massey extrapolation techniques are derived for a doubly symmetric beam with a transverse force applied at an eccentricity to the shear center. A finite element algorithm which takes into account small initial geometric imperfections is presented using simple matrix algebra. The load vs deflection path for elastic cases, can

Design sensitivity analysis of non-linear buckling load

Computational Mechanics, 1988
This paper describes three procedures for calculating design derivatives of the nonlinear critical load. Constraints on the critical load arise naturally in optimal design of structures having nonlinear behavior. The incremental procedures used for nonlinear analysis can fail before reaching the final load level due to buckling or collapse of the ...

Buckling Loads for Stepped Columns

Journal of the Structural Division, 1964
The formulation of exact characteristic buckling load equations for ideal stepped columns is shown. The method is based on the three-step moment equation. This expression, analogous to the well-known three-moment equation, relates the bending moments at three adjacent steps of a slightly buckled column.
