wood-glass bond is proved


Structural analysis

This specialized division focuses on structural analysis in timber engineering and residential timber construction. This encompasses the load bearing capacity and serviceability of walls, roofs and floors with respect to the impact of e.g. self-weight, imposed loads, snow as well as the structural integrity of a building exposed to wind and earthquakes. A special focus is placed on the load bearing characteristics of individual components as well as on the transfer of forces between components via connections.

Research and development

Bracing of residential timber structures

One concluded and two current projects focus on the bracing of residential timber structures by means of different wall and floor systems in timber frame constructions and solid wood constructions. The primary emphasis is placed on the determination via experimentation and calculation of the load bearing capacity of wall diaphragms as well as of connections of elements using different connectors.

The project also aims at developing a practical aid for designing residential timber structures in accordance with Eurocode 5.

Seismic building design

In order to address the more stringent requirements of the Eurocode for buildings with respect to their resistance to seismic loads, a research project was devised together with the technical university of Vienna. Results of this project once again stressed the advantageous seismic behaviour of timber structures due to their low self-weight. The stiffness of solid wood walls and their connections were at the centre of this research project.

Effective wood-glass bond

In a current research project, methods to achieve an effective wood-glass bond in order to utilize the load bearing capacity of floor-to-ceiling glazing are being investigated. The existing characteristics of glass can be used and can provide new architectural and creative stimulus for use of transparent load-bearing components. The quantification of the load-bearing capacity as well as the development of new façade systems are within the scope of this project.

Testing and inspection

Testing of elements for the determination of the load-bearing capacity

  • ÖNORM EN 408 (Determination of the flexural strength of wall and floor elements)
  • ÖNORM EN 594 (Determination of the racking strength and stiffness of timber frame wall panels)
  • ETAG 019 (Prefabricated wood-based load-bearing stressed skin panels)

Additional Services

Development of innovative construction systems

In cooperation with partners from industry, load-bearing elements of timber structures are newly developed and further refined­. To this end personal consultation, assistance in designing and even testing and assessment of prototypes may be employed.
