“…The effects of boundary conditions [8,9], vertical soil pressure [10], soil stiffness [11], vehicle load [12], construction error [13], fatigue behavior [14], shear behavior [15], blast loads [16], and geometric construction [17] on the performance of BC were analyzed efficiently by finite-element analysis (FEA). Philip et al [18] conduct model tests and FEA to examine the properties of top-filling materials affected the bending moment characteristics of BC under bridge design. The study revealed that the use of top-filling material (geofoam) significantly decreases the bending moment at various sections of the BC.…”

Box culvert structure was an essential part of modern infrastructure. Due to the advantages of low pollution and convenient construction, the prefabricated box culvert (PBC) has been gradually utilized in engineering. However, the investigations on load bearing capacity of PBC in different reinforcement forms with same reinforcement ratios were still lack. In the present research, one PBC specimen was tested and discussed by the finite-element analysis (FEA) on load bearing capacity under four-point bending. The load bearing capacity of another three PBCs in different reinforcement forms with the same reinforcement ratios was discussed by the FEA. Results of experimental and numerical investigations showed that: (1) a number of flexural cracks were observed in the midspan bottom of upper slab of PBC, and finally shear failure was observed in bending–shear zone of upper slab of PBC; (2) the number of concrete cracking, plastic deformation of PBC, and stress of rebars reduced by increasing the area of tensile rebars in PBC with reducing the area of compressive rebars under same reinforcement ratios; (3) the ductility and load bearing capacity of PBC increased by increasing the area of tensile rebars with reducing the area of compressive rebars.

“…These structures, subjected to high temperatures resulting from natural and man-made phenomena such as earthquakes and fires, may experience alterations in structural performance [5,6]. It is of high importance, therefore, that the behavior of prefabricated box culverts under conditions of elevated temperature is thoroughly investigated [7][8][9][10].…”

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.
