Wood-Based Construction for Multi-story Buildings: Application of Cement Bonded Wood Composites as Structural Element

摘要

Modern housing and architecture are orientated towards high living quality and low energy consumption. The city of Vienna has put emphasis to introducing wood as a sustainable and ecological material for the building industry in the last decade. With the purpose to optimize structural performance, usability, energy-efficient and ecological profile of wood-based composite systems in several research projects of the Department of Structural Design and Timber Engineering (ITI) the combination of timber products with other conventional building materials and components was explored [3,4, 5, 6]. These technologies provide structurally efficient components for low-energy constructions, support rapid-assembly modular construction with increased efficiency using prefabricated dry elements, thereby open opportunities to reduce carbon emissions. As a representative example for these developments the application of cement bonded wood composites as structural sandwich panels illustrates the extent of the interrelationships involved in the development of complex system solutions to increase resource efficiency.
