The selected parameters for the sensitivity analysis were the following: (1) The Young's modulus, E, of the grid structure members (2) The material mass density, ρ, of the members, The moment of inertia, I, of the members (3) The joints rigidity of the structure.
Since the material of the space grid structure is steel, parameters of steel are precise in FEM and need not be updated.

Introduction Northwestern University in the United States in 1999 for the finite element method Belytschko[1] proposed amendments to the finite element method (material weak intermittent problem and geometric strong intermittent problem) intermittent problems - a method for processing extended finite element method (XFEM ).
The first class is weak because the material properties caused by mutations discontinuity problems,The other is inside the object geometry caused by mutations in the strong discontinuous crack problem is that the representatives of such problems.
