Box girder is an essential structural element in the construction of bridges and other infrastructure projects. It is a type of beam that is shaped like a hollow box or rectangular tube, which provides great strength and stability.
Definitions
A box girder is defined as a structural element that consists of a closed rectangular or polygonal box-shaped cross-section. It is made up of two horizontal flanges and two vertical webs that are joined together by welding or bolting.
Origin
The origins of box girder can be traced back to the early 20th century when engineers began experimenting with new ways to design and construct bridges. The first box girder bridge was built in 1930 in Germany, and since then, the design has been refined and improved upon.
Meaning in different dictionaries
According to the Oxford English Dictionary, a box girder is “a hollow box-like beam used in construction, especially for bridges.” Merriam-Webster defines it as “a structural element that consists of a closed rectangular or polygonal box-shaped cross-section.”
Associations
Box girders are commonly associated with large infrastructure projects such as bridges, viaducts, and tunnels. They are also used in the construction of high-rise buildings and other structures that require a high degree of strength and stability.
