  • RELIABILITY ANALYSIS OF CABLE-STAYED BRIDGE CONSIDERING UNCERTAIN STRUCTURAL PROPERTIES AND INPUT GROUND MOTION

抄録

Structures contain a lot of uncertain factors, such as variations in material and geometrical characteristics. Reliability analysis evaluating variations in structural performance caused by these various variation facots is therefore very important. It is also meaningful to analyze seismic reliability of the entire system if the structures show complex behavior during earthquakes. This study conducted reliability analysis of the whole system of a cable-stayed bridge and evaluated its seismic performance using damage indices which account for (a) maximun deformation; (b) cumulative damage; (c) both maximum deforaion and cumulative damage. Regional earthquake occurence probabilities are evaluated using seismic risk analysis, and seismic reliability considering both uncertainty in structural properties and difference in earthquake occurence probability.
