Optimum design of framed structures with regard to elastic buckling
The purpose of this paper is to develop a general method for optimum design of framed structures with regard to their elastic buckling behavior. In the method proposed here, the finite element method is used for computing the buckling load and Rosen's gradient projection method for optimization technique. To illustrate the wide applicability of this method, some examples of columns and plane portal frames are considered as the problems of finding the optimum shapes to maximize buckling loads for given structural mass and gross geometries. The treated examples contain several basic problems of columns for which exact solutions are known or available, and the corresponding present solutions are compared and found to be in fairly good agreement with them. As for newly treated examples of columns and frameworks, it also seems that reasonable solutions are obtained by proposed method.(Kursetz)
