It is important that we decide a maintenance scenario of a bridge. It is often that it is determined an LCC minimization model to adopt a calculated maintenance scenario. When we calculate LCC, we cannot ignore the influence that a parameter gives a result. For a parameter, it is a deterioration prediction model to calculate from a state transition probability, a life cyclc, discount rate. In this study, we show about a life cycle period and discount rate. An object is for an expensive steel reinforced concrete slab of repair frequency in steel superstructure of a national road. We calculate the influence that a difference of a life cycle and discount rate to set give LCC as a test every maintenance scenario. In addition, support to decide the maintenance scenario that LCC becomes minimization by performing the budget simulation that considered budget limitation shows that it is possible.
