【Abstract】 The paper applies the mixed analysis to calculate the geometric nonlinear stability of space composite structures at construction stage. The approach embodies not only the convenience of employing finite element method, but also the feasibility of solving practical engineering problems. A numerical example shows that the method is effective.更多还原
