“…Prefabricated box culverts, a novel structural component, are gaining widespread attention within the engineering domain due to their rapid construction, minimal environmental impact, and significant economic benefits [1][2][3][4]. However, the unpredictability of high-temperature scenarios in real-world applications, such as fires and high-temperature industrial processes, places emphasis on the safety and temperature distribution of these culverts [5][6][7]. Specifically, the joints, a crucial part of the culverts, play a pivotal role in determining the overall safety of the structure under high temperatures.…”

With the rapid progression of urbanisation and the continual refinement of transportation networks, prefabricated box culverts have increasingly attracted attention as modern structural components. Their rapid construction and environmentally friendly characteristics have rendered them a favoured choice within the engineering community. However, under high-temperature conditions, such as in fires or high-temperature industrial processes, concerns remain about the temperature distribution within these culverts and the subsequent impact on joint performance. Although some studies have addressed the temperature distribution and thermal effects associated with these culverts, most have been grounded in theoretical assumptions or have only engaged in preliminary experiments. In this research, an in-depth analysis of the temperature distribution within prefabricated box culverts under high-temperature conditions and the implications for joint performance is undertaken. Advanced finite element analysis tools are utilised for simulations. The findings provide the engineering community with comprehensive and precise reference data, holding significant implications for the design, construction, and maintenance of future prefabricated box culverts.

“…The predominant focus of extant research methodologies has been placed upon the analysis of prefabricated box culverts under ambient temperature conditions, leaving the phenomena under elevated temperature states somewhat underexplored. Additionally, it has been observed that prior investigations into thermal stress within prefabricated box culverts have typically been constrained to singular loading conditions [14][15][16], thereby overlooking the intricate loading scenarios that may manifest in practical engineering endeavors, such as cyclic loading. Consequently, this has culminated in a partial comprehension of the seismic resilience of prefabricated box culverts when subjected to extreme conditions [17][18][19].…”

In the realm of large-scale underground transportation engineering, prefabricated box culverts have emerged as a predominant structural element. However, their performance is potentially compromised under the duress of high temperatures, prevalent during natural or man-made disasters such as earthquakes and fires. Prior investigations predominantly focus on the performance analysis of these structures at ambient temperatures, leaving their behavior under elevated temperatures relatively unexplored. This gap in research is addressed in this study, wherein the thermal stress-strain relationship of prefabricated box culverts under high-temperature conditions is meticulously examined. A dynamical constitutive model for these structures at elevated temperatures is also proposed, paving the way for a comprehensive analysis of their seismic resilience. The insights gleaned from this study not only furnish theoretical guidance for the design and construction of prefabricated box culverts but also establish a foundational framework for subsequent inquiries in this domain.
