WebHowever, they often misestimate the hysteretic behavior of the structures. Additionally, due to the nature of smeared cracks, the cracks may be diffused. This article proposes a new … Webcracks are formed so quickly that it is very difficult to observe the actual behavior. As the loss of elastic stiffness gives rise to an open crack and the crack is a damage to the structure, the model assumes that cracking causes damage. It is also assumed that there is no permanent strain associated with cracking.
