Almost every structural system is constrained by time, cost, and quality budget. There are many factors that influence the overall cost of any structural system. To achieve the maximum value for money, all costs incurred over the whole life span must be evaluated. The life cycle cost technique has spread widely over different sectors such as buildings construction, manufacturing, railway, energy, and mining. The optimization of the life-cycle cost (LCC) of a project, construction, and equipment is essential for a complex decision-making process. For this reason, the LCC technique applied to structural systems is vital for public and private investors. Current literature recognizes the importance of LCC for the implementation of new structural design criteria and/or for better estimation of the structural behaviour. In general, LCC is also important for resilient infrastructures or cities.

Although many different methods related to LCC are known, they are not widely implemented. Little is known about how practising LCC improves life cycle management in structural systems. Furthermore, the costs generated during the technology operation period can be significant, especially maintenance, repair, and replacement costs. Therefore, they should be considered during the decision-making process. Advanced management of life-cycle costs for different and distinctive structures becomes a challenge for researchers and practitioners since relevant datasets are not commonly available.

This Special Issue aims to provide an overview of the existing body of knowledge and collect recent research findings in the field of LCC. We welcome original research and review articles for this proposed topic. We are also considering submissions discussing computational techniques, probabilistic methods, and mathematical optimization techniques that support life cycle cost analysis and decision-making problems.

Potential topics include but are not limited to the following:

• Life-cycle costing as an assessment tool used in infra-structure projects
• Life-cycle cost analysis as an engineering economic analysis quantifying the differential costs of alternative investment options
• The life cycle cost prediction using stochastic processes
• Structural reliability and fragility analysis over the life span of reinforced concrete and steel structures
• Remaining useful lifetime and maintenance costs of bridges
• Environmental and economic life cycle efficiency in buildings
• Analysis and optimization of structural design in terms of performance, reliability, and cost
