The Berlin Iron Bridge Company was a Berlin, Connecticut, Berlin, Connecticut company that built Bridge, iron bridges and buildings that were supported by iron. It is credited as the architect of numerous bridges and buildings now listed on the U.S. National Register of Historic Places. It eventually became part of the American Bridge Company. History The Berlin Iron Bridge Company began in 1868 as the Corrugated Metal Company, a branch of tinware firm Roys and Wilcox, which is now part of Roper Whitney. Originally producing roofing and shutters, the company became involved in roof trusses. In 1878, under Samuel C. Wilcox, the company purchased the rights to the "parabolic" (lenticular truss) bridge patent from William Douglas. Douglas became treasurer and executive manager of the company. In 1885 he received another patent, and the company name was changed to Berlin Iron Bridge Company. The Berlin Iron Bridge Company constructed hundreds of bridges across the eastern United S ...

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin-jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with the strength to mainta ...
