“…When elasto-plastic analysis is needed, the plastic strain rate must be considered. The strain rate in the plastic domain, in the case of reinforcing steel or in strain hardening fibre-reinforced cementitious composites, is widely adopted as the average value of the hardening phase [32][33][34][35]. For quasi-brittle materials (with softening behaviour) such as plain concrete, the plastic strain rate refers to irreversible components.…”

Extreme loads can arise from accidents such as vehicle collisions or airplane crashes, as well as deliberate acts of terrorism or military attacks involving blasts and fragmentation. Blast overpressure can also occur accidentally, for example, from explosions of hazardous materials such as gas. Distinguishing between accidental and deliberate loads is crucial for designing appropriate protection measures. The repercussions of extreme loading events can be devastating, leading to injuries, loss of life, economic setbacks, and significant social disruption. These consequences result not only from the direct effects of impacts or explosions but also from secondary factors such as structural collapse, which is particularly concerning due to its potential for widespread devastation and substantial losses. Efforts to enhance the protection of concrete structures have focused on understanding the properties of construction materials and how structures respond to impact and blast loads. This document presents a comprehensive overview of RILEM TC 288 “Impact and Explosion,” aiming to provide essential guidance for designing concrete structures to withstand extreme dynamic loads. This emphasizes the importance of a thorough understanding and accurate modelling of loading scenarios and material behaviour. By implementing the strategies outlined in this document, engineers can enhance the safety and resilience of structures facing such challenges.
