The displacement functions in the finite strip method typically restrict
the lateral motion at the loaded ends.
In this article, a finite strip method is presented to release this
restriction for plates under end compression.
The phenomenon of coupling effects of the finite strip method is discussed
and comparison is made between two types of problems: free lateral
displacement is prevented completely or allowed freely.
The single-term finite strip method normally employed in stability
analysis has the advantage of economy, but in some cases it results in
buckling loads which are much larger than the actual one.
Numerical examples are carried out to show the scope of validity of single
An alternative and more versatile procedure is suggested to accurately
predict buckling loads when the single term approach is invalid.
