Earthquake and tsunami vulnerability analysis of highly populated buildings

This research investigates the vulnerability of highly populated buildings in the face of earthquakes and tsunamis, with the AsiaWorld-Expo in Hong Kong, which has a capacity of over 30,000 people, being chosen as a case study. A 3D numerical model of the structure was created using the OpenSees software. A range of earthquake scenarios was used to assess the building's seismic vulnerability, whilst a physics-based methodology was utilised to generate the structure's tsunami fragility curves. The results of this study provide insight into the vulnerability of highly populated buildings and can lead to the development of risk-informed structural design strategies.<p></p>
