Abstract
This paper presents a new time-dependent reliability modeling and optimal maintenance planning approach for residential building components subject to hurricane winds. A gamma process is employed to model the stochastic degradation of components. Time-dependent fragility and failure probabilities obtained from the degradation models are in turn used to determine the retrofit timing that optimize an average cost per cycle time. The method is illustrated on determining the retrofit times of roof-to-wall connections based on actual failure data. Effectiveness of the optimal retrofit age is compared to a replacement age based on time-invariant failure probabilities. It is shown how the effect of wind speed uncertainty on maintenance cost can be quantified using the proposed method.
