Impacts of climate conditions on the performance of infrastructures is a major concern for the sustainability of built environment. The adaptation strategies to climate risks are usually accentuated in high-performance infrastructures, considering projected future climate. Researchers across the globe have tried to characterize this issue through a combination of field experience, modelling, and laboratory investigations, such as those of deterioration models and response indices. However, the integration of these research outputs in risk-based decision support tools that incorporate climate-change scenarios and economic assessment is an unfinished agenda, partly due to the uniqueness of each infrastructure sector, variability of spatial and temporal climate conditions, and benchmarking challenges. Addressing thisissue, this paper analyses climate change impact of tropical cyclone on critical assets and adopts a system dynamics-based framework that couples geographic information system, damage function, and the associated economic assessment to arriveat an optimal decision-making for adaptation strategies of an infrastructure asset. The case study results of coastal infrastructure in Nova Scotia, Canada indicated that the proposed framework could help various stakeholders in understanding and limiting the risks through prioritized adaptation options.
