“…Subjected to multifarious physical and mechanical influences in a complex natural environment, the stability of these structures, particularly concrete bridges, is profoundly affected by environmental factors such as temperature variations [5][6][7][8][9][10][11]. Changes in ambient temperature can induce material expansion or contraction, generating thermal stress that potentially compromises the structural integrity of the bridge [12][13][14].…”

Bridges, integral elements of transportation networks, necessitate high levels of structural stability for secure and seamless operation. Current methodologies predominantly concentrate on the influence of individual factors on bridge infrastructure, often overlooking potential interplays between environmental aspects, such as the symbiosis between thermal stress and load. Additionally, a scarcity of test data for verification and rectification restricts a comprehensive understanding of concrete bridge behavior under complex environmental conditions. To address these limitations, this study focuses on concrete bridges, investigating their thermodynamic properties and thermal stress performance. Initially, an in-depth analysis of the thermodynamic properties of concrete bridges is undertaken. Subsequently, employing a thermal stress-load coupling test, the performance of concrete bridges in intricate environments is scrutinized, and the stress test results are rectified. This study aims to introduce a novel method for evaluating bridge structural stability more accurately and comprehensively, enabling effective responses to varied environmental challenges. The findings from this research possess both theoretical and practical implications for bridge design, construction, and maintenance, contributing towards averting potential structural failures.
