| Abstract: |
| Based on practical assessments, the general method of analyses on seismic fragility of the electronic control cabinets were introduced which consist of getting the premise conditions of analysis, performing qualitatively determinacy analyses to realize the prospective failure modes, performing determinacy analyses to the most risk failure mode to determine the most risk part, and obtaining the seismic fragility degree of the most risk electronic control cabinet through the non-determinacy analysis. Then as experience, some encountered issues and related dealing methods were discussed, including how to replenish the lost premise conditions and choose values of the determinacy and non-determinacy parameters. Meanwhile, the differences between bolt connection and weld connection of the electronic control cabinets were compared in the assessment. These methods made the assessment easier to be carried out and related issues easier to be solved. |
