Abstract
This paper presents a program to optimise structures analysed by the grid model
as a function of the positioning of the supports. An association of the
Displacement Method with mathematical programming techniques, by changing
the positions initially idealised for the supports, seeks to redistribute the stresses
on building slabs by altering the relative stiffness of the elements in order to
allow a greater uniformity of stresses and, thus, to reduce the consumption of
their component materials. In order to verify the effectiveness of the proposed
optimisation procedure, analyses were made of some building slabs following
the new formulation. The choice of these examples was made, basically, for the
purpose of highlighting the effective cost reduction obtained without, however,
disregarding the necessary c
