| Abstract: | Considering the randomness of seismic response and resistance of the pipe,probabilistic forecasting model was built to evaluate the pipe's earthquake disaster.Simplifying the water supply network system as an edge-weighted directed network figure,according to the seismic reliability analysis,each pipeline's damage state was simulated by Monte Carlo random process.Connectivity reliability of the network was measured by graph theory and fuzzy relation matrix method separately.Since precision probability analy... |
