Reliability of reinforced concrete structures designed according to the design codes of Belarus and the Ukraine

The article presents the results of reliability analysis of reinforced concrete structures designed and built in accordance with design codes that are valid in Belarus and Ukraine. It is noted that such structures have different reliability levels as well as failure probabilities. Approaches to assessment loads and actions on structures which are stated in European, Belarusian, former USSR, and Ukrainian standards were analyzed. It is shown that in most cases former USSR and Ukrainian standards do not meet the modern requirements for safety of structures. Additionally the results of reliability-based calibration of partial factors are presented. The calibration resulted in the reduced value of partial factors for permanent loads on precast elements

Reliability level of reinforced concrete members designed according to belarussian national annexes to structural Eurocodes

The article presents the results of reliability analysis of reinforced concrete structures designed and built in accordance with design codes that are valid in Belarus. It is noted that such structures have different reliability levels as well as failure probabilities. Approaches to assessment actions on structures, which stated in European and Belarusian codes were analysed. It is shown that in most cases codes, which are used for designing of the existing structures do not meet the modern requirements for safety of structures. Additionally the results of reliability-based calibration of partial factors using in precast concrete members design are presented. The calibration resulted in the reduced value of partial factors for permanent loads on precast element
