Maintenance and safety of aging infrastructure This book presents the latest scientific research and application practice findings in the engineering field of maintenance and safety of aging infrastructure. The selected invited contributions will provide an overview of the use of advanced computational and or experimental techniques in damage and vulnerability assessment as well as maintenance and retrofitting of aging structures and infrastructures (buildings bridges lifelines etc) for minimization of losses and life cycle cost. Cost competent maintenance and management of civil infrastructure requires balanced consideration of both the structure performance and the total cost accrued over the entire life cycle. Another major problem is that the structure performance is usually reduced during its functioning due to environmental and other factors. Thus current structural condition state is usually assessed by visual inspection or more advanced automatic structural health monitoring techniques. Furthermore maintenance managers often require a list of prioritized maintenance interventions for civil infrastructure on an annual and or long term basis. Various unavoidable uncertainties associated with both randomness (i.e. aleatory uncertainty) and imperfect knowledge (i.e. epistemic uncertainty) also play a crucial role in management and maintenance of engineering systems. Taking into account the aforementioned issues this volume aims to present the recent developments of life cycle maintenance and management planning for deteriorating civil infrastructure considering simultaneously multiple and often competing criteria in terms of condition safety and life cycle cost The purpose of this book is to present the latest research findings in the field of Maintenance and Safety of Aging Infrastructure. For this purpose the aim was to attract state of the art papers that deal with the use of advanced computational and or experimental techniques in damage and vulnerability assessment as well as maintenance and retrofitting of aging structures and infrastructures (e.g. buildings bridges lifelines and naval ships).
