A performance comparison among five optimisation algorithms for the topology design of lifeline network subjected to earthquakes is presented in this study. The topology optimisation model in conjunction with the argument of seismic reliability is firstly introduced for the design of lifeline networks subjected to earthquakes. Subsequently, two quite standard optimisers used in the numerical optimisation, i.e. a genetic algorithm (GA) and a simulated annealing algorithm, are investigated. Their hybrid scheme, entitled a simulated annealing GA that combines the advantages of two standard optimisers, is introduced as well. Besides, an ant colony algorithm and a particle swarm algorithm that have been developed in recent years are explored. Three modelled lifeline networks, including two benchmark networks and one actual network, are used as the numerical carriers that the five optimisation algorithms accommodate. It is concluded that the simulated annealing GA provides an excellent tool with higher efficiency to achieve optimal topology of lifeline networks.
