The finite element semi-analytical method for solving three-dimensional space-filling structure of the waveform. Narrow construction of the structure by bending the reaction matrix. According to finite element displacement field of semi-analytical method expressed as the displacement of two combinations: a functional form to locate the direction to shift shape the other direction for the finite element method for solving algebraic equations. Finally, examples show that: semi-analytical finite element method for solving nonlinear problems of space-filling structure with high precision, fast convergence, easy-to-computer programming advantages. Key words: finite element semi-analytical method three-dimensional filling wave structure thin space system geometric nonlinearity
