Pratt roof truss zero force members
WebApr 16, 2012 · In this chapter we will focus on three types of structures: trusses, frames, and machines. Trusses are often used in the design of bridges. Chapter 6 Objectives Students will be able to:1) Analyze trusses a) define a simple truss b) identify commonly-used trusses c) identify zero-force members d) determine forces in members using the Method of ... WebMar 27, 2024 · Pratt Truss. A Pratt Truss has been used over the past two centuries as an effective truss method. The vertical members are in compression, whilst the diagonal members are in tension. This simplifies and produces a more efficient design since the steel in the diagonal members (in tension) can be reduced.
