Ductile-Fragile Transition: A Novel Comparison Between Fracture Mechanics of Materials and Framed Structures

Abstract

This paper deals with the issue of structural collapse considering an analogy between ductilebrittle transition of materials, taking into account the current literature which also considers the number of fragility and the stress intensification factor in the presence of crack, with extension on a larger scale involving framed structures subjected to increasing vertical loads. It is evaluated the ductile-fragile transition in relation to concrete frames with different structural hierarchy (2x2, 5x5, 11x11).
