The study is intended to propose a systematic procedure for the development of the condition assessment based structures safety and cost effective performance criteria for design and upgrading of bridge structures. A set of cost function models for life cycle cost analysis of bridge structures is proposed and thus the expected total life cycle costs(ETLCC) include initial(design, testing and construction) costs and direct · indirect damage costs considering repair · replacement costs, human losses and property damage costs, road user costs, and indirect regional economic losses costs. Optimum safety indices are presented based on expected total cost minimization using only tree parameters, which are the level of the failure cost to the initial cost(τ), the extent of increased initial cost by improvement in safety(ν) and the order of the initial cost function(n). From the numerical invetigations. it may be positively stated that the proposed optimum design procedure for bridge structures based on the ETLCC will lead to more rational, economical and safer design.

The study is intended to propose a systematic procedure for the development of the condition assessment based structures safety and cost effective performance criteria for design and upgrading of deteriorating bridge structures. A set of cost function models for life cycle cost analysis of bridge structures is proposed and thus the expected total life cycle costs include initial(design, testing and construction) costs, maintenance costs expected strength failure costs and expected service ability failure costs. Optimum safety indices are presented based on expected total cost minimization using only tree parameters, which are the level of the failure cost to the initial cost(τ), the extent of increased initial cost by improvement in safety(ν)and the order of the initial cost function(n). It may be expected that the proposed approach can be effectively utilized for the development of optimal performance criteria for design and upgrading of deteriorating bridge structures.
