Influence of aggregate and interface properties on the impact response and scaling effect of RC beams: A mesoscale study
Beijing University of Technology
Abstract
As a multiphase composite material, concrete exhibits complex mechanical responses under dynamic loads due to the heterogeneity of its internal mesoscopic components. Prototype tests are the most reliable methodologies to explore structural performance under dynamic loads, but they are limited by equipment, technology, and cost. Therefore, researchers typically adopt scaled tests to analyze the structural impact response. However, the dynamic response of the structure may not satisfy the classical similarity law and the reasons are under investigation. In this study, the relationship between concrete heterogeneity and scaling effect was explored preliminarily. Based on the drop hammer impact simulations, the…
