SCI-publication P140 (Ref 1) gives a more exten-sive treatment of steel box girder design. Box Girder Crane DesignsDesigning a box girder for a crane is a complex process that involves several steps and considerations. KTM Engineering has been designing box girders for well over a decade with more than a hundred designs in use around the nation. KTM designs box girders in accordance with CMAA standards.The Design ProcessHere is a general .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 . A novel thermal analysis methodology is proposed to predict the temperature distribution of steel box girders considering the actual wind field. . Along the girder, the grid sizes are arranged between 5.0 and 18.5 mm, with a majority of 12 mm, which is about 1/2500 of the total width of the girder. Around the guardrail, the grid size is near .
The novel type of box girder specimens is composed of cold-formed C-section flanges and sinusoidal corrugated steel webs, as shown in Fig. 1, and three C-section stiffeners are introduced at mid-span and both beam ends.Both the flanges and stiffeners employ the same C-section size, but the stiffener at mid-span experiences mechanical cutting to facilitating the .Committee on Horizontally Curved Steel Box Girder Bridges has conducted a comprehensive survey^ on the details of box girder bridges (straight and curved).

According to The Steel Construction Institute (SCI, 2004), box girder bridges and I-beam bridges require approximately the same weight of steel. However, it has been discovered that composite box girders can be optimized to make the best use of their advantages, which can lead to slightly less steel usage.

At the intersection of the 30-foot girder row (100 psf live load) and the 35-foot beam, find that the range of girder depths to support the 35-beams spaced at 10-foot max. as W21-W24. This table indicates that the 30-foot long girder could be a wide-flange girder with a nominal depth as shallow as 21-inches (W21) or as deep as 24-inches (W24).The ability for the steel box girders to be used economically in long spans as opposed to a concrete or composite section ; . In addition, finite element analysis methods were adopted for the design of the diaphragms to optimise the plate sizes and confirm the design stress flows from the girder webs to the bearings. Footer.After that, the static similitude conditions (ratio of all the corresponding linear dimensions in the model and prototype are equal) are applied to estimate other spans' geometrical properties. .
