This study aims to apply homotopy method to space truss composed of discrete members to obtain a semi-analytical solution. For the purpose of this research, a nonlinear governing equation of the structures is formulated in consideration of geometrical nonlinearity, and homotopy equation is derived. The result of carring out dynamic analysis on a simple model is compared to a numerical method of 4th order Runge-Kutta method(RK4).
