Sensitivity analysis is a crucial step in computational mechanics and earthquake engineering. Sensitivity analysis of a model (either numerical or physical) aims at quantifying the relative importance of each input parameter, their potential interaction, and their effects on the model response. Sensitivity analysis has a long-term application in structural engineering more specifically on reinforced concrete RC structures. Many researchers benefited from the results of sensitivity analysis to reduce the uncertainty domain to those variables which are very important. This further helps in uncertainty quantification by accelerating the entire process. This state-of-the-art technical report provides a comprehensive review of classical sensitivity analysis techniques, followed by an in-depth review of all the related documents that implemented a full sensitivity analysis or partially adopted it for uncertainty quantification-related discussions. This review report on sensitivity analysis of reinforced concrete structures is a valuable contribution to the field of computational mechanics and earthquake engineering. This review highlights the importance of selecting an appropriate sensitivity analysis technique to achieve reliable results in structural analysis and design. By providing insights into the advantages and limitations of various sensitivity analysis techniques, this report can guide researchers, practitioners, and decision-makers in selecting the most appropriate technique for their specific applications. It is observed that the outcome of a sensitivity analysis depends heavily on the applied technique to perform the sensitivity assessment which eventually may cause a significant bias during the decision making. This report paves the road for better selection of a sensitivity analysis technique in problems related to structural and earthquake engineering. The findings of this review have significant implications for improving the accuracy and reliability of structural analysis, ultimately leading to safer and more resilient structures.

“…A sensitivity analysis, by assessing decision variables in uence on the optimization objectives, would identify the most important parameters for the study case. The following optimization would then focus on the greatest decision variables and LCA objectives (Andrianandraina et al, 2015;Ta et al, 2018). The optimization, as well as the inclusion of LCA, would be simpli ed.…”

“…Van-Loc et al [4] made a comparison between the relevant provisions of the Chinese and European codes on durability design of concrete bridges, such as environmental action grade, minimum strength and minimum protective layer thickness, and predicted the durability design life of bridges under carbonation and chloride environment by numerical calculation method. It was considered that the provisions of the two codes could meet the durability of bridges under carbonation environment.…”

In order to study the whole process of corrosion expansion and cracking of protective coatings of reinforced concrete columns under the coupling condition of load and chloride corrosion environment, the transmission characteristics of chloride salts in loaded concrete columns and the deterioration mechanism of cracking and spalling of protective coatings caused by steel corrosion are studied. The transport characteristics of chloride salts in concrete under the coupling condition of load and erosion environment are studied by means of creep tester. The loadbearing levels of specimens are divided into four groups according to the design values of ultimate load: 0%, 20%, 40% and 60%. The transport of chloride ions in concrete in marine environment is simulated by dry-wet cycling method. The results show that the existence of compressive stress accelerates the chloride ion transport in concrete at the initial stage of loading, and the higher the stress level, the faster the chloride ion transport. With the increase of loading time, the stress hinders the transport process of chloride ion. In the same period, the transmission efficiency in concrete without stress is the highest. In the same period, the chloride ion concentration on the surface gradually decreases with the compressive stress level. The longer the time, the more obvious the downward trend. The peak chloride ion content has little change with the increase of the compressive stress level; at the same compressive stress level, the chloride ion diffusion coefficient is basically unchanged with the increase of the dry-wet cycle; in the same cycle, the chloride ion diffusion coefficient increases with the increase of the stress level, but does not show a linear relationship. Using large-scale finite element DIANA (High-end Nonlinear Finite Element Analysis Software), the whole process of rust expansion and cracking of protective layer of loaded concrete column is numerically analyzed.
