Abstract

A previously developed composite meso-model for steel fiber reinforced concrete (SFRC) is
extended in this paper to take into account the effect of temperature on dynamic behavior. The model is
calibrated with SFRC experimental results from characterization tests performed at room temperature
and after exposure to high temperatures. The calibrated model is then applied to the simulation of drop
tests on SFRC beams previously exposed to high temperatures. The results show that the model is able
to reproduce mechanical properties degradation due to high temperatures exposure and the beneficial
effect of fibers under static and dynamic loading.
