An Introduction to Wooden Bridges

Abstract

In this chapter, the reader is introduced to the use of wood in bridge construction. It advances reasons while wooden bridges continue to be relevant in different parts of the world and highlights some of the disadvantages of wooden bridges. Further discussions cover the different types of wooden bridges including log bridges which are still common in many rural areas of Africa; beam bridges which constitute the simplest structural form for bridge spans; covered bridges with roof and siding which, in most cases, create an almost complete enclosure; and truss bridges whose load-bearing superstructures are composed of trusses. The chapter has intentionally avoided the sizing of new bridges or their components because the topic is beyond the scope of this book.
