Abstract
A design technique for the frame structure with the largest buckling l oad will be proposed in this paper. The reciprocal sum of the buckling loads of the structure is minimized with a constraint that the volume of the structural materials should be kept constant. Such an optimal method also means that the structure will approximately take the large st buckling load. The structural problem is formulated by using the ma trix displacement method and the solution is given by an iterative sch eme, while it is not necessary to compute the buckling eigenvalues. So me numerical examples are included. (C) 1997 Elsevier Science Ltd.
