By means of the theory of universal unfolding, the influence of multiimperfections upon the
critical loads of pitchfork structures in engineering is analysed. The estimation formula for lower bounds on
the increments of the critical loads that are caused by imperfections of the structures is given, and a simple
and available numerical method for computing lower bounds is described.
