Reliability-based deterioration and replacement decision model for community buildings

The local government agencies in Victoria are responsible for around $7.6 billion worth of expenditure on capital works and recurrent services each year, and the management of $60 billion of community assets. Among them, commun¡ty buildings are the second largest class of assets that local governments own and manage. As the majority of existing community building stocks are maturing, the local governments seek more reliable deterioration prediction and renewal decision making strategies. This paper presents a reliability based methodology for renewal of communiÇ buildings through building component analysis. Gamma process is considered to be an appropriate approach for predicting deterioration of building elements because it accounts for the temporal variability of degradatio
