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.
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.
Tied-arch bridge is a bridge that carries itself and can be constructed at places that have problems with unstable soil. It can be problematic if it is not maintained properly but there are tied-arch bridges that are over a century old and are still in use.
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.
