In this regard, probabilistic-based approaches offer a valuable means for governments and decision-makers to anticipate and address potential seismic hazards. This paper centers on the seismic risk assessment of cable-stayed bridge portfolios, employing fragility estimation, a robust methodology that quantifies the likelihood of surpassing specific damage or performance thresholds for different bridge types under seismic loading. Fragility estimation provides critical insights into bridge behavior during earthquakes, empowering decision-makers to prioritize retrofitting efforts, allocate resources efficiently, and develop comprehensive emergency preparedness plans. In this study, the seismic fragility of a typical cable-stayed bridge is investigated under the influence of 20 seismic waves. The findings demonstrate that the bridge tower exhibits remarkable robustness, even when subjected to peak ground accelerations (PGA) as high as 1g, with the probability of incurring absolute damage at approximately 30%. However, the bridge bearings display a higher vulnerability, as they may suffer significant damage at PGAs as low as 0.3g, with a failure probability of 50% and 30% for moderate and severe damage, respectively. By employing fragility estimation to assess bridge portfolios, decision-makers can enhance their preparedness and resilience, thereby safeguarding critical transportation infrastructure and ensuring the safety and well-being of the public.<\/jats:p>","DOI":"10.3233\/faia230756","type":"book-chapter","created":{"date-parts":[[2023,10,30]],"date-time":"2023-10-30T08:25:22Z","timestamp":1698654322000},"source":"Crossref","is-referenced-by-count":0,"title":["Seismic Risk Assessment of Cable-Stayed Bridge Portfolios Using Fragility Estimation"],"prefix":"10.3233","author":[{"given":"Zheng","family":"Fang","sequence":"first","affiliation":[{"name":"Hong Kong Polytechnic University, Hong Kong, 100872, China"}]},{"given":"Yinghao","family":"Zhao","sequence":"additional","affiliation":[{"name":"Guangzhou Maritime University, Guangzhou, 510725, China"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Digitalization and Management Innovation II"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA230756","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,30]],"date-time":"2023-10-30T08:25:24Z","timestamp":1698654324000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA230756"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,10,26]]},"ISBN":["9781643684529","9781643684536"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia230756","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,10,26]]}}}
