The three-dimensional truss structure is a structure used in a wide range of fields including space structure. Although there seems to be no new knowledge in this report, it applies to the formulation for performing nonlinear analysis of three dimensional truss structure by introducing extensional strain and its application to the analysis of the folding process of origami structure. Furthermore, we tried to find the equilibrium position when temperature change occurred in the members of the three dimensional truss by adding the thermal strain to the extensional strain. In addition, application of analysis with thermal strain can be able to find the initial equilibrium configuration of tensegrity structure.
