On the added value of multi-scale modeling of concrete

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 1,   Pages 1-23 doi: 10.1007/s11709-021-0790-0

Abstract: This review of the added value of multi-scale modeling of concrete is based on three representative examplesThe structural nature of the high-dynamic strength increase can be explained by using a multi-scale modelThe second example refers to multi-scale thermoelastic analysis of concrete pavements, subjected to solarThe third example deals with multi-scale structural analysis of a real-scale test of a segmental tunnelOverall, it is concluded that multi-scale models have indeed a significant added value.
