Damage assessment of water supply networks due to seismic events using vulnerability functions

The paper presents commonly used methodology for assessing damage of water supply networks after a seismic event. relies on deriving and applying so-called vulnerability function. An overview the existing functions is given together with parameters, primarily related to soil deformations, which are influencing assessment. Also, critical review possibility their use given. Finally, by using two approaches, estimated number damages, associated repair costs, network City Petrinja earthquake December 29, 2020. With total 3 800 new it that costs around HRK 28 million. accuracy these estimates should be verified detailed collection processing relevant data in accordance guidelines.
