Based on these simulations the amount of raw material needed per project is estimated for two timber building systems: one solid and the other hollow. Two of the developed segmentation methods are competitive with the commonly used regular segmentation method in terms of their raw material use.

This paper presents an alternative methodology to find optimum fiber layups for a given tube-shape geometry via a graphical optimization strategy based on structural performance requirements. The proposed technique employs simplified shell element models based on classical lamination theory (CLT) to avoid explicit fiber modeling in the FEA simulations. Lamination parameters are utilized to generate the reduced stiffness matrices for continuous multi-layer FRP lamination. The fiber layup of the component is retrieved from the optimal lamination parameters that maximize the structural performance.
