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.
To enable better utilization of truss structures, engineers and architects from all around the world have devised many types of trusses that can be used for the creation of incredible amount of structures. You can learn more about those truss designs and benefits of truss use here.
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.
Suspension bridges are relatively modern invention (at least those that are built to be large). They are cheaper and can have longer spans but can’t sustain as much weight as other types of bridges. Here are some variants of suspension bridges.
