| Abstrait: |
An approach to robustness assessment of structural systems undergoing continuous damage is presented. Damage is described by means of a dimensionless index associated with prescribed patterns of cross-sectional deterioration and computed through a weighted average over the structural volume based on strain energy. The variation of a performance indicator associated with deformation modes and load participation factors is related to the amount of damage to obtain a dimensionless measure of structural robustness. The proposed approach is applied to structural robustness assessment of an arch bridge under continuous deterioration. |
