Seismic Damage Simulation on Taiwan Water Supply Networks with Negative Pressure Treatment

Seismic Damage Simulation on Taiwan Water Supply Networks with Negative Pressure Treatment

This work is to develop a tool for simulating seismic damages on water supply networks in Taiwan. The tool is based on TELES’s potential earth science analysis and a Taiwan-applicable pipeline repair rate formulation proposed by Liu et al.(2012). The development of the tool follows the seismic damage simulation methods from GIRAFFE, especially the negative pressure treatment. The EPANET library is integrated into the tool to create, update, and analyze the hydraulic model of a water supply network. Graph Theory is employed to remove the solution obstacle: no-flow sub-networks derived by either the modeling of network seismic damages, or the removal of negative pressures.
