  In this work a methodology is proposed for the correction of condition rating to make it dependent on the system behavior.Robustness and Redundancy concepts that have been used in the past for structural design of new bridges and for assessment of existing bridges are in this work extended to condition rating,which represents the first step of bridge health condition evaluation of bridges life-cycle.
