The design principles described in the following is based on the fracture mechanical approach known as the fictitious crack model which relies on the so-called stress-crack opening relationship σw(w) as the basic material input. The design method is applicable for Steel Fiber Reinforced Concretes (SFRC) that exhibit strain softening behavior. The method can also be used for other Fiber Reinforced Cementitious Composites (FRCC) which exhibit strain softening behavior as well as plain concrete (which is assumed always to exhibit strain softening behavior).

Abstract
The design principles described in the following is based on the fracture mechanical approach known as the fictitious crack model which relies on the so-called stress-crack opening relationship σw(w) as the basic material input. The design method is applicable for Steel Fiber Reinforced Concretes (SFRC) that exhibit strain softening behavior. The method can also be used for other Fiber Reinforced Cementitious Composites (FRCC) which exhibit strain softening behavior as well as plain concrete (which is assumed always to exhibit strain softening behavior).File in questo prodotto:
