Enhancing Performance of Engineering Structures under Dynamic Disasters with ECC–FRP Composites: A Review at Material and Member Levels

Dynamic loadings arising from impact, explosive, and seismic disasters impose high requirements on the performance of engineering structures during service periods. Engineered cementitious composite (ECC) exhibits exceptional toughness and crack resistance, while fiber-reinforced polymer (FRP) possesses lightweight and high-strength properties. ECC and FRP composites show promising potential in enhancing the resilience of existing structures under dynamic disaster scenarios. However, most research on ECC and FRP has primarily focused on static properties, while investigations of dynamic properties are limited. This paper provides a comprehensive review of the dynamic properties of ECC and FRP composites followed by a summary of studies conducted on the dynamic behavior of ECC and FRP strengthened members, which provides valuable insights for further research on these materials and their applications in strengthening structures under dynamic disasters.
