Complex Trusses Most practical statically determinate trusses are simple trusses. Occasionally, however, one encounters a peculiarly arranged truss which, whilst statically determinate, has a set of simultaneous equilibrium equations which can not be readily uncoupled. These trusses are called Complex Trusses. Complex trusses lend themselves to a simple computer solution with algorithms resembling those of the more general stiffness analysis of structures. Since all trusses, statically determinate and indeterminate can be solved with equal ease with the stiffness method, there is no real need to cover special methods for statically determinate trusses. The author of these lines has written a Python program for the Complex Trusses which, of course, can also solve simple trusses. If there is an expressed interest in it, I will be happy to add it to this text. Complex Trusses cannot be classified as simple or compound
