In recent years, the concepts of resilience and sustainability have become very topical popular. The concept rose to prominence in late 1980s became a central issue world politics, when construction industry began generate first sustainable building assessment systems with more or less equally weighted environmental, economic, social aspects for office buildings over their life cycles. On other hand, is usually connected occurrence extreme events during cycle structures infrastructures. last...

A lifetime optimization methodology for planning the inspection and repair of structures that deteriorate over time is introduced illustrated through numerical examples. The based on minimizing expected total life-cycle cost while maintaining an allowable reliability structure. This method incorporates: (a) quality techniques with different detection capabilities; (b) all possibilities event tree; (c) effects aging, deterioration, subsequent structural reliability; (d) value money. overall...

Cost-competent maintenance and management of civil infrastructure requires balanced consideration both the structure performance total cost accrued over entire life-cycle. Most existing systems are developed on basis life-cycle minimization only. The single solution thus obtained, however, does not necessarily result in satisfactory long-term performance. Another concern is that usually described by visual inspection-based condition states. actual safety level, has been explicitly or...

Our knowledge to model, analyse, design, maintain, monitor, manage, predict and optimise the life-cycle performance of structures infrastructures under uncertainty is continually growing. However, in many countries, including United States, civil infrastructure no longer within desired levels safety. Decisions regarding systems should be supported by an integrated reliability-based multi-objective optimisation framework considering, among other factors, likelihood successful total expected...

The objective of bridge management is to allocate and use the limited resources balance lifetime reliability life-cycle cost in an optimal manner. As 20th century has drawn a close, it appropriate reflect on birth growth systems, examine where they are today, predict their future. In this paper, attempted shed some light past, present, future highway bridges. It shown that current systems have limitations these can be overcome by using reliability-based approach. concluded additional...

Abstract In comparison with the well‐researched field of analysis and design structural systems, life‐cycle performance prediction these systems under no maintenance as well various scenarios is far more complex, a rapidly emergent in engineering. As structures become older costs higher, different agencies administrations charge civil infrastructure are facing challenges related to implementation structure management based on cost considerations. This article reviews research date...

Analytical investigations into the effects of damage and redundancy on reliability structural systems are reported. These based a definition including both system assessment concepts. Truss bridges analyzed for different scenarios used to develop theoretical concepts illustrate their practical applications.

During the past decade, monitoring concepts for structural systems have been subjected to a rapid development process. They become more and important in intervention planning (e.g., maintenance, repair, rehabilitation, replacement) on new existing structures. Nevertheless, there is still strong need efficient use of data reliability assessment prediction models. Updating models, based data, affect strategies. Since these strategies involve costs, assist spending available budgets. Therefore,...

ABSTRACT This paper proposes a probabilistic approach for the pre‐event assessment of seismic resilience bridges, including uncertainties associated with expected damage, restoration process, and rebuilding/rehabilitation costs. A fragility analysis performs evaluation level damage (none, slight, moderate, extensive, complete) induced on bridges by event. Then, six‐parameter sinusoidal‐based function describes bridge functionality over time. Depending regional hazard, performance that...

In recent years, significant advances have been accomplished in the fields of modeling, analysis, and design deteriorating civil engineering systems, novel approaches to life-cycle assessment, maintenance planning, optimal structural systems proposed. Despite these advances, concepts are far from being explicitly addressed assessment codes effectively implemented into practice. There is, therefore, a need promote further research field performance under uncertainty fill gap between theory...

The development of a generalised framework for assessing bridge life-cycle performance and cost, with emphasis on analysis, prediction, optimisation decision-making under uncertainty, is briefly addressed. central issue underlying the importance approach to engineering need rational basis making informed decisions regarding design, construction, inspection, monitoring, maintenance, repair, rehabilitation, replacement management bridges uncertainty which carried out by using multi-objective...

Structural systems are under deterioration due to ageing, mechanical stressors, and harsh environment, among other threats. Corrosion fatigue can cause gradual structural deterioration. Moreover, natural man-made hazards may lead a sudden drop in the performance. Inspection maintenance actions performed monitor safety maintain performance over certain thresholds. However, these must be effectively planned throughout life-cycle of system ensure optimum budget allocation maximum possible...

After recent large earthquakes, field investigations confirmed that several bridges were severely damaged and collapsed not only due to the earthquake, as an independent hazard, but also subsequent tsunami, landslide or fault displacement. In addition, long-term material deterioration might have important impact on seismic damage bridges. Therefore, it is study both interacting hazards their effects reliability risk of bridge networks. Although earthquake still a dominant hazard in many...

Delivering infrastructure, resilient to multiple natural hazards and climate change, is fundamental continued economic prosperity social coherence. This a strategic priority of the United Nations Sustainable Development Goals (SDGs), World Bank, Organisation for Economic Co-operation (OECD), public policies global initiatives. The operability functionality critical infrastructure are continuously challenged by stressors, increasing demands ageing, whilst their interconnectedness dependencies...

Risk assessment and mitigation programs have been carried out over the last decades in attempt to reduce transportation infrastructure downtime post-disaster recovery costs. Recently, concept of resilience gained increasing importance design, assessment, maintenance, rehabilitation structures systems, particularly bridges networks, exposed natural man-made hazards. In field disaster mitigation, frameworks proposed provide a basis for development qualitative quantitative models quantifying...

The assessment of the current state and prediction future condition deteriorating structures are crucial processes in management civil infrastructure systems. Not only time-varying loads resistances but also a series maintenance interventions that applied to keep structural systems safe serviceable make process very difficult. In order perform realistic life-cycle analysis under different scenarios uncertainties involved this have be considered. This paper considers these by providing...
