OPENING EVENT – room Tirol


Timber construction for the demanding real estate and housing industry

Moderation: Sandra Burlet, Lignum – Holzwirtschaft Schweiz, Zürich (SUI)



The general climate policy situation is causing a change in the values of investors in both the EU and Switzerland: with a view to the sales value of new projects and the value retention of existing portfolios, sustainability will increase from a soft factor to a hard criterion. Surveys of residential and office buildings in Switzerland show that timber construction is not only ecologically superior to solid construction, but can also keep up economically.

Current developments in connection technology

Moderation: Prof. Dr. Gerhard Fink, Aalto University, Helsinki (FIN)



Timber engineering has developed rapidly in recent decades. Wide-span halls and multi-storey residential and office buildings made of wood are now widespread. High-quality and reliable connections are the basic requirement for these developments. New and at the same time more demanding areas of application of the material wood require continuous further development in the field of connection technology as well as the integration of new knowledge into standardization. This year's prologue on connection technology deals with two topics: dismantling and assessment of connections as well as hybrid components, whereby the latter are also considered with regard to their dismantling and sustainability.

Bio-based wood adhesives and CO2-optimized wood-based materials

Moderation: Dr. Simon Aicher, Materialprüfungsanstalt Universität Stuttgart, Stuttgart (GER)



Against the background of the "European Green Deal" and the associated objective of doing business in the EU in a climate-neutral manner by 2050, companies are developing their own climate targets, with a focus on emissions. By decarbonizing processes, it should be possible to avoid burning fossil fuels in the future. However, higher demands are placed on load-bearing components. The agenda is something like the search for the Holy Grail: 100% emission-free adhesives for load-bearing wood-based materials based on renewable raw materials.

Wood structures


Wood structures are unique and different from other structures from an environmental point of view. As a natural and renewable resource, wood has qualities that are vital to our survival. If wood as a building material did not exist, we would have to invent it. Accordingly, all stakeholders in the construction industry are called upon to ensure that wood plays a greater role as a construction material than in the recent past.

Block A – room Innsbruck


Exposed engineering structures

Moderation: Prof. Dr. Philipp Dietsch, Karlsruher Institut für Technologie, Karlsruhe (GER)



Realizing extraordinary engineering structures made of wood has always had a special appeal for planners and builders. In addition to bridges and towers, timber construction has opened up new areas of application in recent years, such as wooden car parkades. But wooden bridges are also increasingly in demand. The revision of Eurocode 5-2 "Timber bridges" comes at the right time. Damage to existing structures also helps to learn lessons for the planning and execution of future wooden bridges.

Robust structures

Moderation: Prof. Michael Flach, Universität Innsbruck, Innsbruck (AUT)



Safety in relation to a possible structural failure should be carefully considered, especially in the case of arenas with large numbers of visitors. Thanks to biaxial load transfer, so-called redundant structures have the ability to dissipate loads through redistribution via different paths. As a result, they do not fail when the limit of one component is reached, but they use reserves of the entire system. The selected examples show interesting solutions on how the efficiency of supporting structures can be increased to make the load-bearing capacity safer.

The National Forest Inventory shows increasing wood stocks, especially hardwood. Damage caused by heat, drought and insects lead to an increase in the amount of damaged wood, especially in the case of spruce. In the future, due to climate change and planned forest adjustments, a decline in conifers and an increase in deciduous trees is expected. What about the usage options for hardwood? Which steps are necessary to promote the efficient material use of hardwood?

Epilog – room Innsbruck


From tradition into the future

The arrival of European and Asian timber construction cultures in the 21st century
Moderation: Prof. Wolfgang Winter, Technische Universität Wien (AUT)



A look at the media shows that urban, multi-storey hybrid timber construction has made a comeback in the 21st century after being almost completely replaced by steel and reinforced concrete in the 20th century. Highly acclaimed examples will be shown from the German-speaking area and Japan. These regions build on diverse and innovative timber building cultures, which also enriched building technology and architecture in the urban context up to the end of the 19th century. The epilogue is intended to discuss the extent to which centuries-old technical and cultural achievements in timber construction have been preserved, despite being suppressed in the 20th century, and can be reactivated and further developed in the 21st century. In addition to technical questions and cultural aspects, this also includes questions of resource availability and the feasibility of a renewed conversion of construction production.
