To The Question of Risk Management for Failures of Cable-Stayed and Prestressed Bridges in Russia

The characteristic cases of cable-stayed and prestressed bridge structures failures and collapses in Russia are considered. Some results of risk analysis methodology applied to bridge structures are given. The process of identification of potential hazards and possible failure modes, definition the critical risk of failure with respect to the bridge structures are described. In order to improve a technical condition of bridge structures and to reduce the risks of their failures and collapses, some risk management actions were suggested with respect to the cable-stayed bridge on the Russian island in Vladivostok. Some of them are given in the report. For example, an inspection monitoring system, founded on new non-destructive equipment, is developed.
