Abstract

A numerical technique is developed for the prediction of the instability load or instability length of a wall with specified end forces. The load-deformation curves with both the ascending and descending branches are predicted by the new technique based on the Newmark’s method for computing the instability load of a beam-column. The concept of equivalent column is used in this study where a beam-column can be substituted by an equivalent column and vice versa.

The numerical technique is applicable for walls with any engineering materials with different properties in both compression and tension. Large deformations effect is accounted for in this analysis. Only walls with uniform end forces are considered in this study. A wall strip is treated here as a plane strain problem.
