    COM3: Existing Concrete Structures

Motivation

The goal of Commission 3 (COM3) is to define appropriate and reliable procedures to establish the safety of existing structures and any associated requirements for interventions to extend the safe operation or working life of such structures.

Scope and objective of technical work

COM3 will deliver this through the preparation of comprehensive guidance for the assessment of existing concrete structures, providing complementary recommendations to those given in the fib Model Code for Concrete Structures 2010 (fib MC2010), which was prepared primarily for the design of new concrete structures. To that end, COM3 will produce documents supporting the development of fib Model Code 2020 (fib MC2020) to be used for the assessment of the present structural performance and the prediction and evaluation of future structural performance of existing concrete structures with or without damage and/or revised operational requirements, together with any associated interventions required to extend their service life. It is envisaged that the documents to be produced could include technical reports, reviews of the state-of-the-art and technical history/evolution, technical guidelines, specifications and recommendations.

  • TG3.1 - Reliability and safety evaluation: full-probabilistic and semi-probabilistic methods for existing structures

    fib Task Group 3.1 (TG3.1) focuses on the reliability and safety evaluation of existing structures and focuses on the development of risk and reliability target levels for assessment and retrofitting, the full-probabilistic modelling of the structural safety and semi-probabilistic assessment methods for existing structures.

    The TG aims to (i) resolve pending questions with respect to the full-probabilistic assessment and target safety levels for the assessment and retrofitting of existing structures, and (ii) support the risk and reliability related questions arising due to the developments in TG3.2, TG3.3 and TG3.4.

    Initially, attention will be given to developing a technical guideline for assigning target reliabilities and making a suitable risk differentiation for existing and monumental structures, considering both individuals and groups.

  • TG3.2 - Modeling of structural performance of existing concrete structures

    It is widely understood and accepted that existing concrete structures are different entities to contemporary new concrete structures. There are numerous flexibilities inherent to the process of the design of new concrete structures and in their construction. Existing structures are entities that can, in principle, be interrogated and assessed to establish their actual nature and condition. However, such processes have their difficulties and uncertainties and it is in fact often very difficult to interrogate an existing structure. These difficulties increase when an existing structure has experienced damage or deterioration. Accordingly, substantial and different uncertainties remain with respect to existing structures and these uncertainties need to be taken into account in the structural assessment process.

  • TG3.3 - Existing Concrete Structures: Life Management, Testing and Structural Health Monitoring

    Task Group 3.3 focuses on the development of a set of practical state-of-the-art guidelines for the assessment and decision-making procedures required for the through-life management of existing concrete structures, focusing on:

    • advanced assessment techniques for the evaluation of existing structures, both in their current condition and taking account of time-dependent changes which may occur to them;
    • simplified assessment approaches for such kind of evaluations;
    • the development of practical decision-making procedures to perform a complete and coherent assessment of an existing structure.

    The initial focus will be on the preparation of technical guidelines for the characterisation of deterioration mechanisms and of suitable prognosis methods that are feasible for practical engineering purposes. At the same time, technical guidelines will also be developed in order to clarify tools and techniques for surveys and monitoring of the addressed deterioration mechanisms.

  • TG3.4 - Selection and implementation of interventions/through-life management activities and measures for concrete structures

    The focus will be on the selection and implementation of interventions and through-life management activities and measures for concrete structures. Its final goal is to provide the draft on intervention for the new fib MC2020. The basic procedure is updating “Chapter 9: Conservation” of the fib MC2010, considering recent progress in this field.

    The initial focus will be on the preparation of technical guidelines for the selection and implementation of interventions dealing with current major intervention methods.

    With respect to through-life management activities and measures for concrete structures, a primary objective will be updating “Chapter 9: Conservation” of the fib MC2010, considering recent technical progress and new ideas.

  • TG3.5 - Forensic engineering

    We have an enormous and an ever-increasing heritage of reinforced and prestressed concrete structures, many of which are currently approaching the end of their intended service life. However, there are pressing societal, economic and environmental needs to safely extend the service lives of many of these structures. This poses a delicate and challenging task if we are to make appropriate decisions on the through-life management and care of these constructed assets to achieve this while avoiding transferring an excessive burden onto the next generation. To do this we need a better understanding of the real behaviours of structures, why they may not achieved the required performance and, ultimately, what may cause them to fail.
