Computational Design of Timber Structures – Linking Form and Mechanics

Student: Vitezslav Stembera


Topic Description

Due to the layered structure of wood-based products and the ever-ongoing modernization of processing technologies (like CNC mills), complex shapes of such products can be realized. Together with their excellent mechanical properties, wood-based products are ideally suited for the use in geometrically complex two- and three-dimensional building structures. Nevertheless, wood is not used as extensively as these very good material characteristics would suggest. The main cause is its quite complex material behavior, the huge variety due to hundreds of species and the mechanical characteristics of wood connections, often significantly influencing the overall structural behavior.
In this sense, the main contribution of this PhD project will be to establish a link between computational mechanical modeling of wood-based products and computational geometric design of timber structures (see Figure below). Based on advanced numerical models for the prediction of the mechanical behavior of wood and on our expertise in architectural geometry, simple application criteria should be derived for selected wooden components and connections, and implemented into computational geometric design tools. Information about the mechanical feasibility of a structure will then be available already in the geometric optimization phase of structural forms.
