The article considers the issues of assessing the risks of failure of structural systems made of reinforced concrete in an accidental design situation. The methods existing in codes and technical literature for determining the target values of reliability parameters and acceptable risk when performing robustness checks of structural systems are considered. A methodology for determining target reliability measures based on criteria of individual and social (group) risks for structural systems made of precast reinforced concrete is proposed. The dependences obtained in the work made it possible to determine the values of the predicted collapse areas, for which the reliability of the structural system is provided by requirements based on individual risk. The article shows that for large areas of collapse, reliability parameters in an accidental design situation should be established on the basis of criteria dependencies for social (group) risk.
