Abstract

In order to address the challenge of accurately quantifying the roughness of the bond interface morphology between Normal Strength Concrete (NSC) and Ultra-High-Performance Concrete (UHPC), this study employed the spatial frequency content method to characterize randomly rough surfaces. The roughness was quantified using the sand filling method, and subsequently, a “Z”-shaped direct shear finite element model with rough bonding surfaces was established. The results indicate that the rough surfaces generated by the spatial frequency content method can be applied to the bonding interfaces of both types of concrete. This approach facilitates the three-dimensional characterization of the bond interface morphology and roughness, yielding reliable simulation results. The failure mode obtained from the finite element model corresponds precisely to the actual observed behavior. Through analysis, it was determined that shear loading is primarily borne by the effective bonded area and mechanical interlocking forces.
