- Abstract:
- To quantify and improve the seismic resilience of urban water distribution networks,an analytical framework for resilience and a recovery strategy based on importance are proposed.Firstly,a functional analysis of the water distribution networks including 4 main components(the water tower,the water pump,the water plant,and the water pipe)is established to obtain the demand-based resilience index of the water distribution networks.Secondly,the fragility models determining the damage of the 4 components are introduced.Then an importance-based approach is proposed for working out a strategy for water distribution networks' post-earthquake recovery.Finally,a case study of a medium-sized water distribution network is done by the importance-based approach.The 4 results of seismic resilience from the 4 approaches—the dynamic importance-based approach,the static importance-based approach,and the other 2 empirical approaches—are compared with each other.It is obvious that the dynamic importance-based approach can significantly improve the seismic resilience of the water distribution networks.
