Treatment of uncertainty in structural Damage Assessment
Reliability Engineering & System Safety, 1993Co-Authors: Dorothy A. ReedAbstract:Abstract Structural Damage Assessment is a process that involves decision-making under uncertainty. Reasoning with or about uncertainty has been the focus of research in many fields in addition to civil engineering, such as decision analysis, philosophy, statistics and psychology. Several methods for the representation of reasoning under uncertainty have been developed. These methods, which the artificial intelligence community refers to as uncertain inference schemes , will be briefly discussed in this paper. One particular scheme, the causal network approach, will be examined in detail. Its application to post-earthquake Damage Assessment will be given. This particular application represents an approach that has not been used in the structural engineering field before.

Response‐based Damage Assessment of structures
Earthquake Engineering & Structural Dynamics, 1999Co-Authors: Ahmed Ghobarah, Hamdy Abou-elfath, Ashraf BiddahAbstract:The structure's ability to survive an earthquake may be measured in terms of the expected state of Damage of the structure after the earthquake. Damage may be quantified by using any of several Damage indices defined as functions whose values can be related to particular structural Damage states. A number of available response-based Damage indices are discussed and critically evaluated for their applicability in seismic Damage evaluation. A new rational approach for Damage Assessment is presented which provides a measure of the physical response characteristics of the structure and is better suited for non-linear structural analysis. A practical method based on the static pushover analysis is proposed to estimate the expected Damage to structures when subjected to earthquakes of different intensities. Results of the analysis of ductile and non-ductile reinforced concrete buildings show that the proposed procedure for Damage Assessment gives a simple, consistent and rational Damage indicator for structures.

Damage Assessment in systemic vasculitis.
Current rheumatology reports, 2008Co-Authors: Luis H. SilveiraAbstract:Systemic vasculitides were initially reported as acute, progressive, severe, and life-threatening diseases. The introduction of glucocorticoids and cyclophosphamide for the treatment of vasculitis improved survival dramatically, but morbidity has remained high. Damage develops as a consequence of recurrent or persistent active vasculitis or its treatment. It is defined as the accumulation of nonhealing scars that are unlikely to respond to immunosuppressive therapy. Damage Assessment is essential in systemic vasculitis because it may facilitate patient stratification in clinical trials and possibly in clinical practice. Moreover, it may avoid unnecessary use of immunosuppressive therapy. The Vasculitis Damage Index, developed and validated in 1997, has been very useful in solving many matters in systemic vasculitis and is currently the only validated Damage-Assessment tool available. However, the vasculitis community has recognized that there is a growing need to improve the evaluation of Damage in vasculitis. The development of a Combined Damage Assessment index, which would permit a more appropriate and standardized approach to disease Assessment applicable to systemic vasculitis, has been proposed.
