1. Safety Level <strong>Based</strong> Assessment• Step 5. <strong>Design</strong> Safety Level‣ Quantitative safety inherent in <strong>the</strong> structural member‣ The actual safety level ensured by <strong>the</strong> structural design proposed‣ It could be estimated c<strong>on</strong>sidering failure probability and operati<strong>on</strong> plan• Step 6. <strong>Structural</strong> Safety Evaluati<strong>on</strong>‣ First, document verificati<strong>on</strong> is necessary• All <strong>the</strong> works d<strong>on</strong>e by designer should be verified to be reas<strong>on</strong>able‣ Sec<strong>on</strong>d, comparing <strong>the</strong> DSL with <strong>the</strong> TSL is necessary• If DSL is not less than <strong>the</strong> TSL, current design is safe enough• O<strong>the</strong>rwise, current design is to be amended to make its structural safetylevel higherThe 6 th ASEF- 8 -
