“…For example, researchers may look at reducing both weight and deflection at the same time (Thompson et al, 2006). Multi-objective optimization problems are more difficult to solve, necessitating the use of more advanced computational techniques (Wang et al, 2021b). Another significant point of contention is that, contrary to multi-objective optimization's fundamental nature, there is no unique solution that accomplishes the best of all objectives at the same time (Dong et al, 2014).…”

PurposeThe purpose of this article is to analyze the optimization process in depth, elaborating on the components of the entire process and the techniques used. Researchers have been drawn to the expanding trend of optimization since the turn of the century. The rate of research can be used to measure the progress and increase of this optimization procedure. This study is phenomenal to understand the optimization process and different algorithms in addition to their application by keeping in mind the current computational power that has increased the implementation for several engineering applications.Design/methodology/approachTwo-dimensional analysis has been carried out for the optimization process and its approaches to addressing optimization problems, i.e. computational power has increased the implementation. The first section focuses on a thorough examination of the optimization process, its objectives and the development of processes. Second, techniques of the optimization process have been evaluated, as well as some new ones that have emerged to overcome the above-mentioned problems.FindingsThis paper provided detailed knowledge of optimization, several approaches and their applications in civil engineering, i.e. structural, geotechnical, hydraulic, transportation and many more. This research provided tremendous emerging techniques, where the lack of exploratory studies is to be approached soon.Originality/valueOptimization processes have been studied for a very long time, in engineering, but the current computational power has increased the implementation for several engineering applications. Besides that, different techniques and their prediction modes often require high computational strength, such parameters can be mitigated with the use of different techniques to reduce computational cost and increase accuracy.

The structural development in bridge engineering along with efficiency have got much attention in few decades. Leading to the development, Optimization of structure established on mathematical analysis emerged mostly employed strategies for productive and sustainable design in the bridge engineering. Despite the widespread knowledge, there has yet to be a rigorous examination of recent structural optimization exploration development. Thus, the primary objectives of this paper are to critically review previous structural optimization research, provide a detailed examination of optimization goals and outline recent research field limitations and provide guidelines for future research proposal in the field of bridge engineering structural optimization. This article begins by outlining the relevance of efficiency and sustainability in the bridge construction, as well as the work done required for this review. Suitable papers are gathered and followed by a statistical analysis of the selected publications. Following that, the selected papers are evaluated in terms of the optimization targets as well as their spatial patterns. Structure's optimization four key steps, including modeling, optimization techniques, formulation of optimization concerns and computational tools, are also researched and examined in depth. Finally, research gaps in contemporary works are identified, as well as suggested guidance for future works.

“…Furthermore, determining the optimal structural cable force is generally not a single-objective optimization problem. In such cases, designers must consider multiple optimization objectives and determine the optimal solution simultaneously [4][5][6] . This paper investigates an optimization method based on a genetic algorithm (GA).…”

This paper proposes a method to better address the optimization problem of cable forces in cable-stayed bridges, particularly when considering multiple objectives simultaneously. It applies genetic algorithms to optimize cable forces and utilizes Pareto theory for multi-objective optimization. The proposed method is implemented using MATLAB software as the programming platform and ANSYS parameterized modeling. Additionally, an actual bridge is used as a case study to validate the proposed optimization method. By minimizing the main beam bending strain energy and the maximum cable force of the cable as objectives with cable force values as optimization variables, the internal force state of the structure is improved by adjusting the cable forces distribution. The Pareto optimal solution is obtained through optimization calculations, reflecting the minimum main beam bending energy that can be achieved under different cable force safety factors. This solution can guide engineering design.
