Going organic: using evolution in civils design

Buildings and infrastructure are starting to look more natural with organic forms resulting from lessons learnt from nature. This paper introduces the genetic algorithm to civil engineering designers. The genetic algorithm is a numerical optimisation method that mimics Darwinian biological evolution. The different stages of genetic design are described: encoding of an individual, creation of an initial population of individuals, assessment of each individual's fitness, and creation of the next generation (creating variation by mixing or by mutation). Civil engineering applications are discussed: truss design and optimisation, prediction of masonry arch collapse load and collapse mechanism, reinforced earth embankment design, and yield-line analysis of complex reinforced concrete slabs.
