Structural and Durability Assessment of Heritage Reinforced Concrete Structures
Reinforced concrete structures built in the first half of the 20th century are part of our cultural heritage. Many of them have been degraded due to environmental effects or extreme actions, although their further utilisation and use are desired.
To maintain a safe operation of historical reinforced concrete structures it is thus necessary to confirm with appropriate assessment methods that the load carrying capacity of the structures sufficient for the current and foreseeable applied loads without accelerated deterioration, and the structures remain serviceable.
Several diagnostic methods are used to investigate the condition of existing reinforced concrete structures. As well as the predominant use of visual inspections and destructive tests, there has been a tendency towards applying non-destructive testing techniques in recent decades.
There is a large potential in an appropriate combination of various techniques, as this combination can improve the accuracy of estimation of the measured properties or help reduce time to obtain the necessary data for assessment.
The paper presents methods of diagnosis, analysis, assessment, service life expectancy and extension for historical reinforced concrete structures. An overview of a selection of available non-destructive, minor-destructive and monitoring methods is given and their efficacy to help analyse and assess condition is discussed. A methodology is shown where in-situ testing methods play a key role in determining input parameters for the assessment. Results of a testing programme via case studies are demonstrated where the efficiency of various non-destructive testing methods have been studied.
