Abstract Timber lattice shells are multi-layered structures of great interest for medium and long span lightweight solutions in structural and aesthetic terms. They are constructed by bending initially straight laths. This curving process can lead to high initial stresses in

Abstract Thermal modification of wood is an environmentally friendly alternative to other preservative treatments which provides improvement in durability and dimensional stability. Heat treatments have been mainly applied to softwoods for non-structural uses. Considering the current abundance of hardwoods such
