This study aims to apply multistage homotopy perturbation method (MHPM) to SDOF space truss to obtain a semi-analytical solution. For the purpose, a nonlinear governing equation is derived in consideration of geometrical nonlinearity, and homotopy equation is formulated. The result of carrying out dynamic analysis on a simple model is compared to a numerical method of 4th order Runge-Kutta method (RK4), and the dynamic response by MHPM concurs with the numerical result.
