报告人简介

Prof Dina D’Ayala is the UNESCO Chair in Disaster Risk Reduction and Resilience Engineering @ UCL. She is Professor of Structural Engineering within the Department of Civil, Environmental and Geomatic Engineering. She is Co-Director of the UCL EPICentre and Co-Director of the StrEnTHE, the Structural and Environmental Laboratory @UCL HERE EAST . She is a Director of the International Association of Earthquake Engineers and Fellow of the ICE. She is a founder member and Scientific committee member of the ICOMOS ISCARSAH. She has been the Chair of the Cost Action FP1101, Assessment, Reinforcement and Monitoring of Timber Structures. Her specialism is Structural Resilience Engineering with particular emphasis on the assessment, strengthening, preservation and resilience of existing buildings, structures, transport infrastructure and cultural heritage.  

Her current research focus is on infrastructure system resilience with the objective of producing interactive platforms to aid stakeholders’ communication and decision making to improve the resilience of infrastructures and communities, based on engineering evidence and rigorous assessment of risk from natural hazards. This critical requirement for sustainable societies can be fulfilled if advanced computing methods are used in intelligent and ethical ways.

Prof D’Ayala has been the Chief Scientist of the World Bank Global Programme for Safer School (GPSS) and she has advised the UK Foreign Office on investments on School infrastructure resilience in Pakistan and Nepal, and the UK Department of Education on a risk model for buildings in their estate.

报告简介：

Fast urban development and changes in climate, increase flood risk, threatening people’s property and life. Flood management actions are mostly focused on large-scale defences, such as river embankments or discharge channels or tunnels. However, these are difficult to implement in town centres without affecting the value of their heritage districts and might not provide sufficient mitigation.  Therefore, urban heritage buildings may become vulnerable to flood events, even when they were originally designed and built with intrinsic resilient measures, based on the local knowledge of the natural environment and its threats at the time. Their aesthetic and cultural and economic values mean that they can represent a proportionally high contribution to losses in any event.

To mitigate this emerging risk localised and tailored mitigation measures are needed. To optimise them, flood vulnerability needs to be studied at the scale of the individual building. The talk will illustrate a multiscale methodology, called PARNASSUS, to assess the flood vulnerability and risk of residential buildings. PARNASSUS is based on a wide range of parameters, from building-specific to neighbourhood conditions and catchment area conditions. The vulnerability model can then be combined with high-resolution fluvial and pluvial flood hazard maps to develop qualitative and quantitative risk. A damage function of generic applicability is developed to compute the economic losses at individual building and sample levels. The talk will illustrate applications of the methodology in different contexts.
