This study analyzes the behavior of reinforced concrete (RC) members impacted by vehicles or trains by reviewing existing experimental and numerical work. RC structures are susceptible to such collisions, which can cause structural failure or collapse. The damage response depends on the energy transferred during impact, ranging from cosmetic effects to full structural failure. To properly characterize damage, indices are defined considering concrete and steel strain rates during and after plastic deformation. Concrete spalling is also discussed as an indicator of localized or global failure severity. Experimental results from other studies are presented and compared to theoretical models. The latest provisions for incorporating strain rate sensitivity into material models based on various standards are reviewed. This analysis aims to provide insights for better assessing the reliability of RC members after impacts. Understanding reliability is important for evaluating the safety of damaged structures and mitigating risks. The findings can help practitioners evaluate damaged structures and guide future design to avoid severe outcomes from vehicle and train collisions onto critical infrastructure.

By applying asymmetrical lateral impact forces on RC specimens, the specimens’ cross-sectional shape is analyzed. The effectiveness of the RC specimens’ resistance to impact was examined using a drop hammer. Performing research on the factors that led to the failure of various RC specimen shapes and the dynamic responses they exhibited. In the experiment, eight circular and square specimens were used. Includes the method of failure, the impact force, and the deflection time history. The findings point to shear fractures between the point of impact and the adjacent support. The right side of the impact point has suffered significant damage, and the shear tests on all specimens failed. The peak impact force that square specimens can bear may be greater than circular ones. Protecting the concrete core and reducing maximum deflection are benefits of using a square specimen. When the ratio of stirrups is raised, there is only a little variation in the square specimen’s damage range. This may cause a slight reduction in damage, but it is not significant. The plateau force of a circular specimen can be increased, but only a little. An increase in the stirrup ratio may increase energy use.
