Database of the Round-Robin Test on Creep Behaviour in Cracked Sections of Fibre Reinforced Concrete organised by the RILEM Technical Committee 261-CCF

Abstract

[EN] The RILEM Technical Committee 261-CCF launched in 2015 an international Round-Robin Test (RRT) program to improve the knowledge on the long-term behaviour of cracked Fibre Reinforced Concrete (FRC) sections and assess all the different testing methodologies available. The participation of 19 international laboratories performing creep test following different methodologies in compliance with previously agreed conditions contributed to the success of the RRT. A convention regarding the data collection during the RRT was established to simplify the analysis of results. The RRT provided an extensive database of results from tests performed according to similar procedures and conditions agreed beforehand by the participants. More than 150 parameters and variables were defined and registered during the RRT realisation for each specimen. The long-term tests performed on 124 specimens for one year following four main creep methodologies provided a huge database with more than 15000 data. The analysis of this RRT should support the future proposal of standard test procedures and conditions, defining common criteria for future experimental programs for each test method as well as validation of models to consider creep in the design of FRC structures. The database of the RRT is offered open access to the scientific community as supplementary material of the Round-Robin Test State-of-the-Art Report published by Springer in the RILEM State-of-the-Art Reports series to improve the global knowledge in the long-term deformations of the cracked FRC specimens.
