Life-cycle performance, management, and optimisation of structural systems under uncertainty: accomplishments and challenges 1
TLDR
In this paper, the authors highlight recent accomplishments in the life-cycle performance assessment, maintenance, monitoring, management and optimisation of structural systems under uncertainty, and identify challenges in this area.Abstract:
Our knowledge to model, analyse, design, maintain, monitor, manage, predict and optimise the life-cycle performance of structures and infrastructures under uncertainty is continually growing. However, in many countries, including the United States, the civil infrastructure is no longer within desired levels of performance and safety. Decisions regarding civil infrastructure systems should be supported by an integrated reliability-based life-cycle multi-objective optimisation framework by considering, among other factors, the likelihood of successful performance and the total expected cost accrued over the entire life-cycle. The primary objective of this paper is to highlight recent accomplishments in the life-cycle performance assessment, maintenance, monitoring, management and optimisation of structural systems under uncertainty. Challenges are also identified.read more

Contribution for sustainable management of reinforced concrete structures subjected to chloride penetration
TL;DR: In this article, the authors proposed an extension to environmental criteria in view to find sustainable maintenance solutions for corroding reinforced concrete (RC) structures placed in marine atmospheres, where chloride penetration generates corrosion of the reinforcing bars reducing the RC durability.

Critical issues, condition assessment and monitoring of heavy movable structures: emphasis on movable bridges
F. Necati Catbas,Mustafa Gül,H. Burak Gokce,Ricardo Zaurin,Dan M. Frangopol,Kirk A. Grimmelsman +5 more
TL;DR: In this paper, a relatively less studied class of structures is presented based on the research conducted on Florida's movable bridges over the last several years; however, none of these studies provide a comprehensive documentation of issues related to the condition of movable bridge populations in conjunction with possible monitoring applications specific to these bridges.

Prognosis and life-cycle assessment based on SHM information
Dan M. Frangopol,Sunyong Kim +1 more
TL;DR: This chapter deals with the statistical and probabilistic aspects for efficient prognosis using SHM data and the concepts of the statistics of extremes and decision analysis are employed for cost-effective monitoring planning considering availability of monitoring data and performance prediction error.

Probabilistic impacts of corrosion on structural failure and performance limits of reinforced concrete beams
Fatemeh Aslani,Mehdi Dehestani +1 more
TL;DR: In this paper, reliability analyses were performed on the performance of concrete structures in two limit states of serviceability and structural capacity, and the costs caused by the failure in the life cycle of reinforced concrete beams were evaluated and optimized using renewal process analysis in the capacity limit state.

Optimal inspection and maintenance planning for deteriorating structural components through dynamic Bayesian networks and Markov decision processes
TL;DR: Partially Observable Markov Decision Processes (POMDPs) provide a principled mathematical methodology for stochastic optimal control under uncertain action outcomes and observations, in which the optimal actions are prescribed as a function of the entire, dynamically updated, state probability distribution as discussed by the authors .
