The webinar .that differentiate curved steel girders from their straight counterparts include the effects of torsion, flange lateral bending, their inherent lack of stability, and special constructability concerns. Also, the complex behavior of horizontally curved bridges necessitates the consideration of system behavior in the analysis.
To investigate the fatigue performance of an orthotropic steel deck (OSD 1) in a long-span highway suspension bridge with a wide steel-box girder, a finite element analysis (FEA) and a model test were conducted. The fatigue stress characteristics and stress-influence surface of typical fatigue details of the OSD were investigated.

Using the EBEF method on closed (or quasi-closed) box girder analysis provides a .Steel box bridge girders generally exhibit both aesthetic appeal and structural efficiency [1].Designed with single-cell or multi-cell cross-sections, steel box bridge girders have the advantages of being lightweight, possessing high torsional stiffness, and allowing for rapid erection [2].As a result, they have been widely utilized in the design of highway interchanges . Structural Analysis; Structural Steel; Composite Box-Girder Bridges; Composite Box-Girder Bridges. By admin / April 15, 2024 . Box girders have several favorable characteristics that make their use desirable for spans of about 120 ft and up. Structural steel is employed at high efficiency, because a high percentage can be placed in wide flanges .
In the 1970s, several steel bridges in Europe collapse due to the local buckling of stiffened plates and steel box girders, causing a shock in the field of bridge engineering [7].Subsequently, numerous investigations on the stability behavior of steel plates and steel box girders are conducted by many scholars worldwide, such as Ichizou et al. [8], Frieze [9], . Since the first edition of the AASHTO Guide Specifications for Horizontally Curved Steel Girder Highway Bridges was published in 1980, there have been two more editions including many revisions to the specifications. Some changes were based on valid research results and others were based on limited or uncertain research results and information.applications in which the girders have been used in straight bridge applications to match adjacent prestressed concrete U-beams. In these cases, straight steel box girders are used in regions where the clear span requirements preclude the use of the concrete U-beams. 17. Key Words Steel, Box Girders, Trapezoidal, Torsional 18.
