Chapter 4 - Material properties and high-velocity impact responses of a new hybrid fiber-reinforced engineered cementitious composite (ECC)

Abstract

Residential and commercial buildings, infrastructures, and protective structures, especially defense structures, may be subjected to impact loadings during their service lives. The impact of the aircraft that hit the World Trade Center Twin Towers in New York in the 2001 terrorist attack is a typical example of an impact on civilian infrastructures, while the impact from in-service bullets to a military fortification is that of an impact to defense structures. Research on construction and building materials, which exhibit excellent impact resistance to low- and high-velocity impacts have attracted great interest over the decades. Hybrid-ECC materials exhibit high resistance in high velocity impact with their high strain hardening behavior.
