So, how to TIG weld copper? The steps to TIG welding copper are: TIG welding copper is not hard, but it doesn’t get done that often. It is different than steel, but it is straightforward enough. You can’t treat copper-like steel; the little details are various. Pay attention to those, and your project will be fine.

The concrete box girder is one of the most commonly used structure forms for bridges because of its large flexural and torsional stiffnesses. However, with the increase of span length, the self-weight of a concrete box girder may increase rapidly, which restricts its use in long-span bridges [1].One of the most promising ways to reduce the self-weight of bridges is to .

1. Introduction. As a relatively new addition to modern bridge design, the prestressed concrete (PC) box girder bridge with trapezoidal corrugated steel webs (TCSWs) has gained popularity among engineers and researchers alike, owing to its excellent load-bearing performance and innovative structural design.
The prestressed concrete box girder with corrugated steel webs (CSWs) is a new type of steel–concrete composite bridge. The substitution of conventional concrete webs with CSWs not only make full use of the shear capacity of steel webs but also the flexural capacity of the concrete slabs, in addition to considerably reducing the weight of the superstructure.“Quasi plane assumption and its application in steel-concrete composite box girders with corrugated steel webs.” Eng.

Based on the traditional hanging basket cantilever construction of the prestressed concrete box girders, combined with the excellent shear capacity of the corrugated steel webs (CSWs), this paper introduces an improved cantilever construction method for long-span prestressed concrete (PC) girder bridges with CSWs, which is called the asynchronous .
Prestressed concrete (PC) girders with corrugated steel webs (CSWs) are a new type of girders that can take full advantages of the material properties of the concrete flanges, prestressed tendons, and steel webs. The materials of the prestressed composite girder are concrete, steel plates, rebars, prestressing tendons and PBL connectors. .

First of all, steel webs, instead of concrete webs, are efficient in reducing self-weight. Moreover, using corrugated webs allows one to avoid using stiffeners usually needed in flat plate webs, and provides a convenient solution to the problem of prestress losses. Since the first prestressed concrete box-girder bridge with corrugated steel .
In a prestressed concrete box girder bridge, the need to contain and deviate the longitudinal tendons of the internal prestressing increases the web thickness and the self-weight of the deck.

TL;DR: In a prestressed concrete box girder bridge, the need to contain and deviate the longitudinal tendons of the internal prestressing increases the web thickness and the self-weight of the deck as discussed by the authors.
The CSW box girder bridge is a new type of girder bridge that was developed in the last century and is widely used in many types of large, medium, and small bridges owing to its various advantages [] (presented in Figure 1.A CSW box girder and its structural parameters are presented in Figure 2, which shows the CSW (where a w, b w, c w, d w, θ w, h w, L w, and t w . Prestressed concrete box girder with corrugated steel webs is a relatively new form of bridge superstructure, and the corrugated steel web has been long recognized as the most typical shear carrying member. To clarify the shear behavior of this type of box girder, theoretical analysis, and literature survey are conducted and the latest findings .
