APPLICATION OF RELIABILITY TO IN-SERVICE MONITORING AND MAINTENANCE OF PARKING GARAGES

In this study, the use of reliability concepts to make informed decisions regarding in-service monitoring and maintenance is demonstrated. Parking garages are used as an example application. The degradation of the driving surface, as defined by the percentage of floor surface delaminated, was used to describe the deterioration process. The delamination is related to corrosion of the reinforcing steel accelerated by Cl- ions (chloride ions) deposited in the concrete lattice from deicing salt laden vehicles. A limit state function relating the degree of delamination to the garage and other influencing parameters was developed and used in a first-order reliability method algorithm to evaluate repair intervals and treatments such as polymer impregnation, vacuum treatments, boiled linseed oil, and absorptive form liners. Considerable savings in maintenance costs may be achieved through optimum scheduling and choice of garage surface treatment.
