The purpose of this study is to get analytic solution of space truss using homotopy perturbation. A homotopy perturbation was derived by formulating a governing equation for a space truss, and a semi analytical solution was obtained by homotopy perturbation. In conclusion, the analytical solution of the simple nonlinear model using the homotopy perturbation was compared with the numerical analysis result.
