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

II Latin American Congress of Timber Structures + II Ibero-Latin American Congress of Timber in Construction (CLEM+CIMAD 2017), Buenos Aires, Argentina.

Abstract Timber gridshell structures get their shape by curving on site initially straight timber laths. This curving process produces stresses in the laths that can easily reach values close to the allowable ones. These initial bending stresses are partially reduced

II Latin American Congress of Timber Structures + II Ibero-Latin American Congress of Timber in Construction (CLEM+CIMAD 2017), Buenos Aires, Argentina.

Abstract The necessary revision of the construction processes in search of more sustainable solutions leads to the use of high efficiency structural systems and environmen-friendly materials. In this sense, timber gridshells represent a solution of great interest for lightweight roofs
