| Abstract: | In this paper the orthogonal and ortho-laid
space grids are assumed as an orthotropic sandwich plate,
which is analyzed by the theory of plate with consideration
of shear deformation and three generalized displacements.
The calculating formulas for internal forces and displace-
ments of double-layer space grids under local loading are
given based upon ESPM, and have been validated by the
finite element method (ANSYS). In general, the differ-
ences between ESPM and FEM are less than 10% and 5%
for internal forces and displacements, respectively. So this
method can be used in the design of double-layer space
grids. |
