The nonlinearity in structural analysis is introduced by considering material properties or large deformations and geometrical changes in a structure and elements. This paper treats a nonlinear problem due to the material property in the analysis of pin-jointed trusses. As the stress-strain diagram is treated as an assemblage of short straight elements of finite number, the nonlinear property can be accurately introduced in the analysis. The computaion is carried out by the incremental-variable elasticity procedure. Numerical examples and corresponding considerations are given to five types of pin-jointed trusses.
