abstract = {The recognition of vulnerability in water distribution system is a critical aspect regarding infrastructure resilience evaluation. Water supply system is represented as a complex network of interconnected distribution mains and nodes spatially distributed over a large area. This study proposes a method of resilience analysis of the existing pipelines in water distribution system for Vancouver, British Columbia as a function of failure in pipelines or repair rate for common seismic hazards incorporating the seismic vulnerability index applied in a Geographical Information System (GIS). The paper presents an outline of quantitative assessment of risk, based on the identification of governing parameters influencing the pipeline behavior, particularly for West Point Grey, Vancouver, BC as the area is prone to high seismic attacks. The pipeline behavior is considered as a function of parameters like pipe diameter, length, and materials, etc. which are demonstrated having a coefficient. They represent individual influences on the links connected to nodes of the system, and the seismic vulnerability of each pipeline is determined using empirical formulas in context with transient ground deformation (TGD), permanent ground deformation (PGD) and liquefaction impacts. The concept of integrating the Vulnerability Index (VI) with damage rate with a graphical map is to carry out a clear understanding of the efficiency of emergency response of each element in the system and prioritizing the potential pipeline candidates for replacement. This method will allow adopting a risk-based strategy to withstand seismic vulnerabilities in the water system of Vancouver.<br/> &copy; 6th International Structural Specialty Conference 2018, Held as Part of the Canadian Society for Civil Engineering Annual Conference 2018.
