内容記述タイプ Abstract
内容記述 This paper introduces a systematic method for LCC(Life Cycle Cost) evaluation of civil engineering infrastructures. LCC evaluation requires a series of modeling, that is, modeling of functionality of target structures, maintenance activities, uncertain events caused by various conditions of target structures and its environment, incurring costs and so on. Authors are developing a LCC evaluation system which encompasses all of those aspects so that can be a practical tool in real managemental situation. This paper introduces a framework of LCC evaluation system and the idea of each sub-part that constitutes the framework. This paper especially focuses on two parts of the system, i.e., modeling of functionality of structures and maintenance activity. Regarding functionality modeling, authors point out that civil engineering infrastructures can be categorized into two types from the point of view of LCC modeling, that is, self-deteriorating structures and structures exposed to uncertain natural hazards. Based on the categorization, two types of models are introduced for expressing functionality of structures, Markov model and hazard-fragility model, and then described is how they are applied in LCC modeling. For LCC evaluation, maintenance activity is necessary part to be modeled as well. This paper also describes how maintenance activity is built in the two types of models mentioned above. In Markov modeling, maintenance activity is regarded as a transition process from worse states to better states, while in hazard-fragility modeling, maintenance activity is expressed as change of fragility curve. Finally computer software system being developed by authors is introduced. This system consists of multiple parts, that is, modeling of structures, maintenance activity, events caused by various conditions of infrastructures and costs associated with all stages of LCC modeling. Each part is briefly described with its features, and then this paper concludes with introducing future development of the system being planned by authors.
