Determination of the Safety Zones According to the Bearing Capacity of Overloaded Structural Elements

The study presents a Methodology of finding the Safety zones of structural elements undergoing extreme overloading, whereas the structure retains its bearing capacity. The methodology is applied to a set of diffusively strengthened concrete beam elements. Two cases of element deformation are considered – Case 1 (elastic deformation), and Case 2 (elastic deformation accompanied by compression micro-damage). Safety zones are outlined within a Space of events introduced by the authors. Their areas have different dimensions in Case 1 and Case 2, characterizing the degree of structure safety under overloading.
