Algorithm mimics natural selection to evolve optimal structure.
The new town hall for Tallinn, the capital of Estonia, is a structure composed of 13 intersecting boxes, each of which cantilevers a considerable distance from inset columns at ground floor level. The side walls of each box are blank and therefore provided the opportunity to hide the arcHitect supporting cantilevering trussed frames.
The RCD group used the theory of genetic design to evolve and engineering solution that went beyond the traditional structural typology of a truss to deliver a more
The genetic algorithm was originally developed by John Holland in the 1960s and is a computer simulation of Darwinian evolution.
The engineers’ genetic algorithm solver initiated a population of possible truss arrangements which were assessed against a performance-related fitness criterion – in this case the deflection of the trussed frame. The resulting solution, which could not have been intuited using guesswork or traditional engineering assumptions, is the best optimised solution that effectively reduces deflection.
