The description of each procedure was directly provided by the participants and follows the same structure for each participant where institution identification and contact information was included. Each participant summarised the most significant data such as specimen's size, load configuration, parameters or environmental conditions in a quite useful table. Moreover, the participants included description and close-up pictures of the creep frames construction, the support boundary conditions, and the measurement devices used. Finally, the participants provided a complete description of the specific complete creep test procedure followed.}, language = {en} } @incollection{LlanoTorreSernaCavalaroetal., author = {Llano-Torre, Aitor and Serna, Pedro and Cavalaro, Sergio H.

A coordinated effort was required to improve the knowledge on long-term behaviour of cracked FRC sections and assess the different testing methodologies available. The RILEM Technical Committee 261-CCF launched in 2015 the round-robin test (RRT) on creep behaviour in cracked sections of FRC program. This chapter includes the introduction and background to understand the realisation of this RRT. The main objectives as well as the limitations of the scope of the RRT are explained. The structure of the book is presented to provide a first overview of the book content. Finally, information about institutions involved as well as geographic distribution of RRT participants and number of specimens tested in the RRT is provided.}, language = {en} } @incollection{LlanoTorreSernaCavalaroetal., author = {Llano-Torre, Aitor and Serna, Pedro and Cavalaro, Sergio H.

The use of 124 specimens for creep tests for one year following four main methodologies provided a huge database with more than 15,000 data. The main statements and conclusions derived from the RRT database analysis are summarised in this section.
