Summary	A new homogenisation approach was applied for the analysis of composite isogrid structures. This approach allows to make the optimisation of the isogrid structures faster. The mathematical model has been verified by means of the comparative analysis for the homogenised model and exact FEM model. Results of the analysis are presented and discussed.
