be directly applied to bridge girders with variable cross-section properties. In order to alleviate the situation, Heins and Hall (1981) prepared a designer’s guide to steel box-girder bridges as a Bethlehem publication with a series of figures and charts. In Europe, Dabrowski (1968, 1972)
Box girders are usually considered for footbridges only for spans over about 30m, and most box girder footbridges adopt an all-steel configuration. The advantage in using an all-steel configuration is that the whole cross section, including parapets, can be fabricated at the works for delivery and erection in complete spans; the weight of such spans is modest and easily . Bridges design based on prescriptive normative rules regarding loads and their combinations, safety factors, material properties, analysis methods, required verifications, and other issues that are included in design codes. In addition, Composite Steel Box Girder (CSBG) bridges present a prominent structural solution for straight and curved bridges with moderate . Bridges often improve the visual appeal of urban landscapes by incorporating curve elements to create iconic forms. However, it is noteworthy that curved bridges have unique mechanical properties under loads compared to straight bridges. This study analyzes a spatial three-curved steel box girder bridge based on an actual engineering case with a complex .
of steel box girder bridges. INTRODUCTION Box girders have become a prominent element in the con struction of major river crossings, highway interchanges, and transit systems. These types of structural elements are particularly attractive because of their high torsional stiffness, which is required when the bridge is curved.The main design effort involves sizing the individual girder sections for the predetermined segments with the objective of minimizing the self-weight of the girder. A typical section for composite .

A box girder concrete beam is a type of beam that is made up of a hollow box section. The box section is typically made of concrete, but it can also be made of steel or a composite material. The box section is designed to provide strength and rigidity, and the extended wings help distribute load. Concrete Box Girders are available a typical width of 12’ (3.66 m), .
Based on an analysis of the extant literature, this paper summarizes the research progress on the mechanical properties and long-term behavior of corrugated steel web (CSW) box girder bridges. First, the research results of CSW box girder bridges in terms of the shear buckling performance (local shear buckling, overall shear buckling, and interaction buckling), bending .W series girders are produced with rebar stirrups protruding from the top flange which are typically bent in the field to accommodate the reinforcing steel of the cast in place deck that these girders support. Benefits of WF girders: Long span capability; .

The authors [7] introduced a novel type of cold-formed steel box girders assembled from C-section flanges and sinusoidal corrugated webs by self-drilling screws, and conducted a comprehensive experimental and numerical study on the structural performance of such box girders. It was indicated that the bending moment was carried by the C-section . The box-girder bridge has recently gained a lot of popularity because of its serviceability, stability, and structural efficiency. The box-girder bridge also has a lower structural weight than any other type of bridge. However, the analysis of such a bridge is too complex and challenging for the designers. This paper offers a modelling process for the study of a box- .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 .
