Abstract

This paper is concerned with the optimal layout of long-span double-layered grids of constant depth consisting of a system of vertical plane trusses. A systematic method is developed for finding the minimum-weight layout for various types of boundary and loading conditions, taking the external load as well as the selfweight into consideration. In estimating the total weight of the trusses, it is assumed that the weight of the chords and web per unit length is proportional, respectively, to the absolute value of the bending moment and shear force acting on the truss. It is shown that for long-span truss grids the structural weight function is very sensitive to changes in the layout and, therefore, structural optimization achieves a significant saving in material consumption. Finally, a non-numerical computer algorithm for the selection of the optimal structural layout is described.
