Reliable computational prognoses of the structural integrity and serviceability throughout the lifetime of structures require the realistic consideration of the damage behaviour of the construction materials for various loading scenrios including static and cyclic loading, environmental loading processes such as moisture and heat transport, corrosion processes, freeze-thaw actions and possible interactions...
Exemplary Realization of Lifetime Control Using Concepts as Presented HereIn the following two possible applications of the lifetime control concepts proposed within this book are examplarily presented.
Mechanical loading and ambient actions on civil engineering structures and components cause lifetime-related deteriorations. Not the rare extreme loading events are in the first place responsible for the evolution of structural degradation but the ensemble of load effects during the life-time of the structure. It is of major importance to have models at hand which adequately reflect the experienced...
Lifetime-Related Structural Damage EvolutionStructures deteriorate during their lifetimes, e.g. their original quality decreases. In terms of structural safety, this reduces the original safety margin, a process, which also can be described as an increase of structural damage. If, in such deterioration, the safety parameter decreases below the admissible safety limit, or the structural damage parameter...
Based on the modeling of external as well as internal actions with respect to lifetime-oriented design (see Chapter 2), and by either applying or adapting various deterioration models of materials and structures (see Chapter 3), a methodological approach and implementation of appropriate concepts, numerical methods and solution paradigms are required to facilitate practical design to reality tasks...
Safety and reliability are important for the whole expected service duration of an engineering structure. Therefore, prognostical solutions for different building types are needed and uncertainties have to be handled. Life-cycle strategies to control future structural degradations by concepts of appropriate design have to be developed, in case including means of inspection, maintenance, and repair...
