Abstract

The life-cycle structural robustness is generally investigated with respect to the initial time of construction, when the structure is intact. However, in the evaluation of life-cycle robustness of existing structures it may be of interest to evaluate the impact of deterioration on the structural performance with reference to the actual damage state and performance level existing at the time of inspection and/or assessment. In this paper, a robustness criterion presented in previous works is extended to consider the influence of the damage level on the time-variant robustness of existing concrete structures over the remaining structural lifetime. In addition, the role of the importance of the structure in the assessment of the life-cycle robustness is considered. The effectiveness of the proposed approach is shown through the application to the deterministic and probabilistic assessment of the life-cycle robustness of a reinforced concrete pier of an existing bridge.
