The manuscript describes a multiscale paradigm for predicting post-cracking flexural behavior in ultrahigh performance fiber reinforced concrete (UHPFRC) structures. A comparative study was conducted to simulate the flexural behavior of reinforced UHPFRC beams used in the Malukou Bridge, China. In this study, UHPFRC was modeled as a heterogeneous composite medium made of a matrix and steel fibers using a reduced-order multiscale approach, and for comparison purposes, using a conventional single-scale homogeneous isotropic medium. The multiscale approach has been shown to be considerably more accurate in predicting the post-cracking flexural behavior of the reinforced UHPFRC deck than the conventional single-scale approach.
