Samenvatting

When a compressive member is designed, it is important to avoid lateral buckling. In order to achieve a higher
buckling load, one may enlarge the cross section of the element, improve the boundary conditions, or put an elastic
support in the middle of the member. Different morphologies of stayed columns have been proposed as an efficient
system. In this paper, three different morphologies are presented. A first morphology is a stayed column with one
cross arm, hinged or fixed to the central column, and four stays (Figure 1.a). A second shape is a stayed column with
several hinged cross arms, symmetrically positioned along the central column (Figure 1.b). Finally a stayed column
with one split up cross arm, hinged to the central column is presented (Figure 1.c). The influence of the different
geometrical parameters and the optimal pretension are studied. A tool for designing these members, taking
imperfections into consideration is presented. Furthermore these stayed columns are compared to the Euler column
with regard to their efficiency (the minimal volume in order to sustain the same given load).
