“…For predicting the life of steel structure components, the formula used in the numerical model was derived by referring to the models proposed by Jo [16] and Santecchia et al [20]. To measure the life of the component, information on characteristics, such as elastic modulus, fatigue coefficient, and stress amplitude, which can express the physical behavior, is required.…”

Noise barrier tunnels (NBTs) comprise prefabricated components that are easily replaceable, reusable, and have the capacity to improve performance when applied to components as their replacements. Reusing NBTs is more price competitive and environmentally friendly than producing new components. However, determining the remaining life of components before they need to be dismantled, using existing NBTs and their maintenance methods, is a considerable challenge. Therefore, this study used a prototype of the digital twin of an NBT to predict the condition and life of tunnel components using numerical behavior analyses. The prototype of the digital twin used in this study could be used to analyze behaviors using a gyro sensor, thereby enabling life analyses. Girders are structural components that have shorter life expectancies than components close to the ground. Component analysis results indicated that our proposed method confirmed changes in the life of girders and column components. Moreover, a negligible change in the life of the purlin component was confirmed. Life cycles management using digital twins can help reduce NBT installation costs, facilitate resource recycling, and make the installation process eco-friendly as they can aid in identifying components that require replacements in the initial designing stage and establish a procurement plan.

A review on the application of the theory of critical distance towards concrete

et al. 2018

Theory of Critical Distance (TCD) is one of Fracture Mechanics numerical model that has gone through tremendous laboratory works and validation. Hence, it has been proven to be precise in broad perspectives in the field. Recently, TCD research related to fracture, especially fatigue on concrete are growing but the depth of study is still shallow and deficient compared to metal and steel. Thus, this made the fracture assessment in concrete obscures and governs by uncertainties. Previous efforts have managed to optimize TCD but the results only valid if the water-cement ratio of a concrete specimen in its optimum level. When the water-cement ratio is adjusted to a higher or lower from its optimum level, the output errors showed inconsistency as reported by Luca Susmel (2016). Therefore, this research aims to optimize the Theory of Critical Distance (TCD) by incorporating water-cement ratio and the interaction of microstructure matrix. The optimization involves few stages and finite element. If Theory of Critical Distance (TCD) can be improved by considering concrete’s additional element in its mathematical expression, it will definitely contribute to betterment in assessing concrete infrastructure around the globe.
