Structural steel trusses
Analysis
Structural analysis uses the concept of resolving forces, which can be analytically or graphically.
Estimating sizes
There is considerable design flexibility for roof trusses, but simple rules can be used as initial guidelines.
Graphical method
The same analysis can be performed graphically, with forces represented by lines drawn to scale in the same direction as the corresponding forces.
Introduction
A truss, or lattice structure, is a structural assembly of small interconnected elements.
Practical considerations
Real circumstances are generally different from the idealised conditions assumed in the analysis of trusses.
Vierendeel girders
Trusses can have a rectangular configuration, avoiding the potential intrusion of diagonal members, if the joints are rigid.
