Model code 2020
The vision for fib Model Code for Concrete Structures 2020 (MC2020), as a single merged general structural code, goes beyond the point reached by fib MC2010, recent ISO codes, such as ISO 16311, and the current Eurocode activities to extend their application to existing structures. The envisaged development is intended to result in an internationally recognized and comprehensive fib Model Code 2020 for new and existing concrete structures. This work is to be taken forward by TG10.1: Model Code 2020. It is clear from discussions at the TC that Commission 10 and TG10.1 should have wide international representation.
The fib Model Code for Concrete Structures 2020 is only available in PRINTED version. The electronic version is accessible via the online viewer depending on your subscription but a PDF version cannot be purchased nor downloaded. Please select the DHL shipment as your delivery option when you make your order.
Model Code Plan users and fib Subscribing Membres will have access to the Model Code and supporting documents online.
Please check the MC2020 plan below. If you purchase it now, you pay CHF 140. The plan is valid until 31 December 2024.

fib MC (2020) presents new consensus guidance on developments relating to concrete structures and structural materials, as well as providing a basis for future codes for concrete structure. It addresses significant advances made on a wide range of issues including those relating to structural design and analysis methods, seismic design and assessment procedures, durability, structural monitoring, service life design, structural assessment through-life and making interventions to adapt existing structures or enhance their performance to accommodate revised requirements or extend their useful life.
fib MC (2020), like previous editions of the fib Model Code, not only specifies requirements and recommended practices, but gives explanations in the adjoining informative column of the document. -

Databases
Scope and Context
Following the need for model calibrations for current and future fib’s Model Codes, as well as other international standards, there is an international necessity to agree on representative test data and to provide it in Open Access as findable, accessible, interoperable and reproducible (FAIR). These data, independently validated and organized in the form of databases can be used in a transparent manner by multiple teams of researchers.
To date, numerous databases exist on different topics, such as shear, bond, shrinkage and creep. These existing databases are, however, mostly offline and static, and do not allow simple and simultaneous access, preventing their collaborative use. In addition, multiple instances exist on a single topic (with potentially different interpretations of the same test data).
Since February 2021, the fib is working on establishing a number of harmonized databases, with the following objectives:
- To create a fib database with a common data structure, that can be used for different types of tests
- To have easy (automated) import of data from existing databases
- A common data structure allowing for data mining across task groups, generating potentially useful data for other purposes
- To provide access to the sources of the data
- To have commonly-agreed databases by the scientific community, useful for code calibration
- To provide continuity and preserve the efforts of fib’s task groups and their members, merging efforts from a global community of researchers
- To have the results publicly and freely available under Open Access and FAIR principles
- To produce scientific publications
- Data will be collected by stable groups and not by individuals, making data collections more transparent but also persistent
Databases are projects developed for a long period of time by many researchers. The work of some researchers is to include new test data in the database, while others check if the tests are relevant and have been properly developed. The databases are a project of the research community. Therefore, it is crucial to acknowledge all the participants for the work they have done in the long process of developing the databases. In the fib, we have done our best to recognise each person for the work done in each database. If any person or organisation thinks that further acknowledgements should be given to other persons, please contact the fib Secretariat or the editor of the relevant database so their request can be considered.

Punching Shear Database
The punching shear database gathers a wide collection of concentric punching tests of two-way reinforced concrete slabs at interior locations without shear reinforcement collected from tests reported in the literature. The “collected test result” database was jointly developed by fib Working Party 2.2.3 (effort led by RWTH and EPFL) and ACI Committee 445 (effort led by Carlos Ospina and other contributors) through a fruitful collaboration that started in 2013, cemented on test data gathering efforts undertaken earlier by both groups. The database was further enhanced by test data stemming from Rupert Walkner’s 2014 PhD thesis, and from previously unpublished work, and later reworked and verified extensively by fib WP 2.2.3 and ACI 445 contributors. The database includes more than 400 collected tests thoroughly documented with realistic dimensions and physical parameters.

FRC Residual Strength Database
The database on residual flexural/tensile strength of fibre reinforced concrete (FRC) gathers data from FRC characterization tests carried out across the world. The database encompasses different characterization tests (standardized and non-standardized), a wide range of FRC classifications (including softening and hardening flexural/tensile responses) and fiber types (material and geometries). The database aims to provide researchers with ample data for model calibrations and practitioners with practical information on the feasibility of FRC for structural purposes.

Corroded Prestressing Database
The database on the mechanical performance of corroded prestressing strands gathers data from experimental tensile tests carried out across the world. The database encompasses: (1) the corrosion type, natural or artificial, (2) the geometry and uncorroded mechanical properties, (3) the mechanical properties and the corrosion morphology and (4) the mechanical behaviour results from tests on corroded samples. In case of natural corrosion, additional information can be provided concerning the prestressed concrete members from which the samples are retrieved and environmental conditions. The database aims to provide researchers extensive data for model validation and calibrations concerning degraded prestressed concrete structures.
