摘要：Providing safety of structures is one of the main aims of design. Intraditional design it is achieved by designing structural components against specifiedlimit states. However, as showed the Ronan Point collapse in UK in 1968, when a gasexplosion in one of flats on the 18-th floor of the residential building caused the failure ofan entire section of the building, this approach is not sufficient. The approach does notexclude the risk of local damage to a structure due to accidental events that can occurduring service life of the structure. While probability of occurrence of such events forordinary structures is low, and, therefore, they are not considered explicitly in design,their effect on structural safety becomes significant if the structure is not robust, that iswhen some local damage can trigger a chain reaction of failures causing collapse of thewhole structure or of a major part of it, the so called progressive collapse.The purpose of this paper is to outline the basic premises for the utilization of riskassessment in evaluating the robustness of structures. In the following the robustnessassessment is understood as a process of decision making based on risks.
