ABSTRACT
Trusses are extremely efficient structures in a building because the individual members carry loads solely through tension and compression, even though the overall form bends like a beam. This chapter describes the basics of how to establish external equilibrating reactions of trusses, as well as any internal equilibrating axial force in any particular member, using the Modern Müller-Breslau Method. This chapter focuses more on two-dimensional, planar trusses, but three-dimensional spatial trusses are also shown. The chapter closes with several études for deeper study and practice.
