Predicting model of creep strain for self-compacting concrete

Abstract

Currently, many models for predicting creep of concrete have been developed by organizations such as: International Concrete Association, European Committee for Standardization, Japan Society of Civil Engineers, etc. Some models have also been adjusted to suit the creep of self-compacting concrete (SCC). However, these models still have relatively large errors when predicting creep of SCC. This paper presents the creep prediction model of SCC FIB-SCC2024, which is built on the basis of reference and adjustment from the original model, the MC2010 fib model, with significantly improved accuracy and higher than some other models in predicting creep of SCC. The database used in model building includes data from 168 creep curves of 32 documents published from 1998 to 2023. The application of the FIB-SCC2024 model in the design calculation of structures using reinforced concrete will contribute to reducing construction and maintenance costs and improving the durability of the structure.
