common l d ratio for simply supported steel box girders Maximizing Girder Span/Depth Ratio One of the design challenges for this three-level interchange was minimizing girder depth as much as possible, to lower ramp profiles and thus create . Is the guage numbering (thickness) for wires and sheet metal the same? Sheetmetal guage is called the U.S. Standard Gauge which the photo is showing. Its used for measuring iron and steel. American Standard which is not the guage in the pic. You just have to buy the correct guage. Last edited by mbgmike; 06-27-2009 at 07:31 PM.

There’s a different vibe to the [metal] genre. The industry as a whole seems to crave authenticity and then in the metal world, it’s like a dirty secret to let people know that you have a job in a bar when you come off tour.
Box girders are used for footbridges curved in plan, bridges with longer spans and cable-stayed bridges with a single plane of stays. All-steel construction is typically used, for lightness. A single box girder as the main longitudinal spine of the bridge is an excellent solution for such situations.

Although the general theories are applicable to larger .depth ratios (L/d) ratio starting from 15 to 19 and different span to depth ratios (L/d) are considered as follows.

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.common for the I-beam form of composite bridges can be utilised to produce box girder structures of clean appearance whilst maintaining relative simplicity and speedy construction procedures. The deflection difference ratio in simply supported RC box girders is a maximum of 0.60%, while the stress difference ratio is a maximum of 7.72% and a minimum of 2.51%, so considering the axial equilibrium conditions has more effect on the stress than on the deflection.

Roof and building specifications often use “gauge” when stating the required material thickness. A structural engineer will call for 20 gauge steel deck, for example, or a roof consultant will specify 24 gauge steel panels to be used in a standing seam metal roof.
