On the added value of multi-scale modeling of concrete

Abstract This review of the added value multi-scale modeling concrete is based on three representative examples. The first one concerned with analysis experimental data, taken from four high-dynamic tests. structural nature strength increase can be explained by using a model. It accounts for microstructure specimens. second example refers to thermoelastic pavements, subjected solar heating. A sensitivity respect internal relative humidity ( RH ) has underlined great importance an assessment risk microcracking concrete. third deals real-scale test segmental tunnel ring. turned out that enables more reliable predictions crack opening displacements in segments than macroscopic models codes practice. Overall, it concluded have indeed significant value. However, its degree varies these In any case, assessed means comparison results sources, namely, analysis, conventional and experiments.
