Durability monitoring of existing reinforced concrete structures: concepts, advancements, and prospects

Abstract

Abstract This article explores the fundamental concepts related to the durability of existing reinforced concrete structures, focusing on its monitoring. It compares the current approach adopted in major projects with that applied to other structures in service. It presents the principles of Structural Health Monitoring (SHM) and examines various sensor solutions available on the market and developed in research projects. It emphasizes the feasibility of democratizing structural monitoring, which is currently limited by cultural barriers. To achieve this, it highlights the need for collaboration among technical professionals, researchers, professional associations, and government agencies to overcome the challenges that have led to the so-called “control blackout” in the built environment.
