Research Abstract

Since one of our country policies toward cost curtailment is minimization of the life cycle cost of various institutions and structures, some computer programs have been developed by respective construction companies and software firms.
However, deterministic approach in almost programs is adopted without regard to the physical uncertainties related to structural safety and reliability such as material strength, circumstances of construction sites, others. On the other hand, probabilistic method is used to estimate numerically the structural safety in consideration for their inevitable uncertainties.
In this study, a computer program which is able to be calculated the life cycle cost of reinforced concrete structure members under damage from salt was developed based upon structural reliability theory, because the method to evaluate structural safety and reliability with reliability index is recommended in International Organization for Standardization, namely ISO 2394. Repair and reinforcement of a structural member subjected to deterioration by salt are judged by crack width and reliability index respectively.
The result of this study is to develop the computer program by which expected LCC of a reinforced concrete structural member under damage from salt is able to be valuated first. Further, some useful results related to maintenance plan of reinforced concrete structures were obtained based upon parametric studies by usage of the developed program.
