讲座主要内容：

In the wake of major seismic events such as the 2011 Great East Japan earthquake and the 2016 Kumamoto earthquake, field investigations have revealed that numerous structures within coastal cities, including bridges and bridge networks, suffered severe damage or collapse. This damage was not only due to seismic forces but also resulted from subsequent tsunamis, landslides, and fault displacements. Additionally, long-term material deterioration can significantly compromise the structural integrity of these infrastructure. Consequently, it is crucial to undertake comprehensive studies on multiple hazards and their compound effects on the reliability, risk, and resilience of coastal infrastructure systems. While seismic activity remains a predominant threat to coastal cities in earthquake-prone regions, a holistic life-cycle reliability and risk assessment must address all potential hazards, including the impacts of climate change. This lecture presents an integrated approach and explores strategies to ensure the reliability, mitigate risks, and enhance the resilience of coastal cities, with a particular focus on bridges and bridge networks exposed to multiple hazards. The theoretical concepts and methodologies are illustrated through case studies of infrastructure systems within coastal cities.
