Comparative Study of Simple Truss Solved According to the Theories of 1st and 2nd Order

Abstract

This contribution deals with the simple planar asymmetric pin-connected truss with 3 members. The ways and methods of derivations and solutions according to theories of first and second order and other possible linearizations are shown (i.e. internal forces, reactions, elongations, stresses). There are applied linear and nonlinear approaches and their simplifications via Taylor's series. Finally, the errors of all approaches are evaluated and compared.
