N2 - Reliability measures a structure's acceptable or unacceptable performance over its service life. To achieve optimal efficiency, a threshold level must be defined. If reliability is lower than this threshold, structural and non-structural damages may occur. If it is higher than the threshold, the structure's cost may increase. This threshold limit is referred to as target reliability. Target reliability in structural engineering ensures safety by preventing structural failures, cost-effectiveness by optimizing materials and construction methods, and sustainability by extending service lives and minimizing environmental impact. It is crucial for achieving adequate performance, cost-effectiveness, and resilience in structural engineering. This article provides a review of the fundamentals, theories, implementation, and applications of structural target reliability (STR). In this paper, STR discusses various aspects, influencing parameters, and the STR method's future prospects. The literature review for this article focuses on STR calibration and STR-based cost optimization methods. Each section is defined in accordance with the existing methods for the main problem, mathematical relationships, and all around STR research. The existing methods for the STR problem are introduced in this article, and the improvements reported on this problem during this time are summarized. These improvements could include increasing accuracy, simplifying the problem, increasing calculation efficiency, and developing a new method for implementing the STR problem. Finally, a general overview of the STR problem is presented, as well as new research opportunities.
