Wood Fibre Insulation Boards as Load-Carrying Sheathing Material of Wall Panels

摘要

To date wood fibre insulation boards (WFIB) are used as thermal and acoustic insulation in timber construction. As wood-based panels, WFIB are also suited for the transfer of loads caused by wind and earthquakes in timber frame construction, where they may replace plywood, particle boards or OSB. This new field of application of WFIB has been analysed in a research project at Karlsruhe Institute of Technology. In order to calculate the load-carrying capacity of wall and roof panels the characteristics of WFIB as well as those of joints with WFIB and dowel-type fasteners need to be known. In tests these characteristics were determined. A proposal is made for the calculation of timber-WFIB-joints with dowel type fasteners. Furthermore the stiffness properties of timber-WFTB-joints were determined. In this paper the results of the tests are presented.
