Risk Assessment and Vulnerability Analysis of a Coastal Concrete Heritage Structure

Abstract

This research focuses on the risk management of reinforced concrete heritage constructions in coastal environments, with an emphasis on preserving their cultural significance. It addresses a critical gap in existing risk-related research, since this type of heritage site is often overlooked in heritage conservation research. The proposed methodology offers a flexible framework that links natural and human-induced hazards with their impacts on key heritage values, enabling the development of appropriate mitigation and adaptation strategies and policies. Climate change-induced threats are also incorporated, allowing for more effective adaptation plans to safeguard concrete coastal heritage for future generations. The Ocean Swimming Pool in Matosinhos, Portugal, designed by the Pritzker Prize winner Álvaro Siza, serves as a pilot study to illustrate the practicality of the risk-based approach, considering its coastal location and exposure to various hazards. By using this case study, the research provides a roadmap for preserving and adapting heritage constructions in similar coastal settings. The integration of cultural values into risk management and conservation policies is a significant contribution of this research. It advocates for a proactive approach that considers the dynamic challenges posed by climate change while preserving the significance of cultural heritage. The adaptable nature of the proposed methodology allows for broader applications, potentially benefiting multiple heritage sites in coastal regions. Ultimately, this research calls for positive changes in risk management practices to ensure the preservation and longevity of culturally significant reinforced concrete heritage sites.
