“…Due to the large longitudinal stiffness of steel plate webs, the use of steel plate webs instead of concrete webs is not conducive to the application of the prestress of a box girder [4]. Although the 'accordion' effect of corrugated steel webs is beneficial to prestressing [5][6][7], when the span of box girder bridges is large, the stability problem of corrugated steel webs is prominent, and additional stiffening is required [8]. Replacing concrete webs with steel truss webs not only leads to a lighter dead weight but also mainly subjects bridges to axial force, with a clearer force transmission path and better stability than corrugated steel webs.…”

An experiment was conducted on a prestressed concrete (PC) composite girder bridge with steel truss webs to investigate its flexural performance. The mechanical characteristics and failure modes of a PC composite girder bridge with steel truss webs was clarified. Finite element (FE) analysis was carried out, and the influence of the girder height-to-span ratio and eccentric loading effect on the flexural performance of a composite beam bridge with a steel truss web was discussed. The method for calculating the cracking bending moment, the bending moment at the rebar yield stage, and the ultimate bending moment of a PC composite girder with steel truss webs was proposed. Key findings include that, in both the elastic and cracking elastic stages, the strain of the bottom and top conforms to the plane-section assumption. Throughout the loading process, there was no occurrence of joint failure or local buckling failure in the steel truss webs; the composite girder ultimately fails due to excessive deformation, indicating that the overall mechanical performance of the composite beam is good. The deflection and stress in the mid-span section decrease with an increasing height-to-span ratio, and there are significant impacts of eccentric loading on deflection and stress. Compared with the results of the FE analysis and test, the calculation methods of the cracking moment, reinforcement yield moment, and ultimate moment of PC composite girders with steel truss webs presented in this paper have a high accuracy.

“…By concentrating on shear buckling stress and failure modes, Kim and Park [19] examined the sensitivity analysis of sinusoidal steel webs and discovered a specific correlation between design variables. Sebastiao and Papangelis [20] employed finite element analysis to calculate the elastic shear deformation of beams featuring sinusoidal corrugated webs. By considering the aim of increasing the shear capacity of narrow plates in a fabrication-intensive manner, Wang et al [21] suggested a method for generating low-frequency sinusoidal patterns on the plate.…”

Existing studies often rely on deterministic numerical analyses for structural models. However, test results consistently highlight uncertainties, particularly in variables such as magnitude of the applied load, geometrical dimensions, material randomness, and limited experiential data. As a response, researchers have increasingly turned their attention to probabilistic design models, recognizing their crucial role in accurately predicting structural performance. This study aims to integrate reliability-based analysis into the numerical modeling of sinusoidal-web steel beams. Two sinusoidal-web beams are considered. The web and the flange thicknesses, in addition to the magnitude of the applied load, are treated as random variables with mean values and standard deviations. Notably, the study demonstrates the efficiency of the reliability index as a governing limit in the analysis process. A detailed comparison between deterministic and probabilistic designs of sinusoidal-web beams is conducted, focusing on the impact of introducing the nature of randomness. Therefore, this study’s results deepen our understanding of how uncertainties significantly influence deformations and stresses.
