| Abstract: | Transient structure is involved in the process of bridge’s construction.From the perspective of supplementing the results of hazard identification,construction of reliability-based security risk analysis method for transient structure was proposed.Then,the model of transient structure was established to analyze the reliability of transient structure.Thus, identification and analysis method of security risk in the process of bridge’s construction was improved,which provides a new way of analytical control of transient structure. |
