ƒ^ƒCƒgƒ‹i‰pjF METHOD OF EVALUATING EARTHQUAKE SAFETY OF RC BRIDGE SYSTEM BASED ON RELIABILITY THEORY
´˜^i‰pjF This study proposes a method of calculating the failure probability of a structure and its structural members during an earthquake. Reliability theory and a Markov process are used to calculate the failure probability of a structure and the probability of damage to its structural members from the time the earthquake commences up to any arbitrary time The characteristics of these techniques mean they are able to quantitatively evaluate changes in damage over time based on failure probability and damage probability. On the basis of the proposed method, a safety evaluation is carried out a bridge system consisting of bearings, RC piers, and pile foundations during an earthquake. This evaluation elucidates the effects of failure of and damage to bearings, bridge piers, and pile foundations on the safety of the bridge system as a whole.
