A howe truss bridge design includes vertical members and diagonals that slope up towards the center. Its diagonals are under compression under balanced loading. It was invented in 1840 by Massachusetts millwright William Howe. Howe truss design proved to be instrumental not only in the development of several notable bridges at the end of an era of fully wooden bridges but also as an inspiration for the creation of other popular designs.
There are three main bridge areas which include all the basic components of bridge: Foundation, Substructure, and Superstructure. Bridges are complex structures, and since they can be made with many different materials and truss types, their components are almost too numerous to count. Here you can get informed about basic bridge parts and components.
Bridges are structures that need to be built to withstand incredible external forces and last for decades or centuries. Sadly many bridges have succumbed to their wounds and took with them many human lives. Here you can find some of the most famous bridge disasters in human history.
Over the last 3000 years, engineers and architects have devised many ways of building bridges. Here you can see for yourself bridge types that are in use today, from what materials they are made, and for what uses are they built.
