Moulded grating is a lattice of connected beams that has wide applications in
various industries. In the case of structural applications, deflection control is
usually expected to be the limiting factor in design rather than strength control.
Thus, this research is mainly focused on an analytical solution to predict the loaddeflection
behaviour of a moulded grating under concentrated and uniform loads. The
general differential equation of an orthotropic plate is expanded by considering a
moulded grating as several beams with bending and torsional rigidities. Afterward, the
developed model is validated by a finite element modelling technique as well as by the
experimental data provided by 8trongwell Company. Results showed that the data
obtained by the proposed analytical model and those of the finite element method and
experimental are in good agreement. Thus, using a developed closed form solution
method in this article, the deflection of a grid with any arbitrary dimensions and meshes
can be calculated properly.
