| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 98 === In view of the large damage suffered in recent typhoons, in order to protect life and reduce damage and loss to an acceptable level, satisfactory performance at a reasonable cost, the building life-cycle cost need to be carefully considered.
The structural limit states are response acceleration at top of building and windows of building. The major considerations in a lifecycle cost analysis are proper treatment of uncertainties in the demand and capacity and costs incurred due to unsatisfactory performance. The uncertainties in the loads and resistance are modeled by random processed and random variables. In considering uncertainties, it is important to recognize two broad types, the aleatory type and epistemic type. Costs of construction, consequences of structural limit states including damage, revenue loss, death and injury as well as discounting cost over time are considered.
A method is proposed for modeling the uncertainties and evaluation of the expected life-cycle cost of an engineering system under a hazard.
