Thermal coupling optimization of bridge environmental impact under natural conditions

Abstract

[EN] Infrastructure is a crucial aspect of promoting worldwide economic integration. However, the construction of infrastructure often results in high energy consumption and substantial emissions of greenhouse gases. Over time, the environment can also cause significant damage to bridges, leading to repeated repairs and replacements that further harm the environment. This research aims to minimize the environmental impact of bridge maintenance over a 100-year lifespan. The study utilizes a three-dimensional dynamic thermo-mechanical optimization model developed through comprehensive research and interdisciplinary collaboration in various fields such as Bibliometrics, Fluid Mechanics, Structural Dynamics, Thermoelectricity, and Damage Mechanics. From examining single crystal structures at a microscopic level to examining system components under extreme temperatures, this study provides a system for reducing environmental pollution. The model's reliability is shown through a case study, demonstrating a reduction of 49.9 million tonnes of emissions, equivalent to 1.91% of total design emissions, over a 100-year maintenance period. This research provides a foundation for future studies and presents an approach for evaluating the environmental impact of long-term temperature changes in structures.
