Important results from the project
The overall aim was to expand the applicability of CLT for multi-story buildings and large-span structures by improving flexibility and increasing predictability in demanding design situations. The research has focused on in-plane shear loading, notches and holes in plates, and joints. The project has contributed to the development of reliable and rationally based design methods for CLT elements and joints. Such efforts are very important for the further development of modern, safe and material-efficient wood-based construction.
Expected long term effects
Modelling approaches for CLT at in-plane shear loading and at beam loading conditions have been developed and a proposal for a rationally based and uniform design method for both cases has been published. Development of numerical modelling and experimental tests regarding load-bearing capacity for plates with notches and joints between elements have contributed to knowledge building. Expected effects of these efforts are increased applicability for CLT in general and opportunities for safer and material-efficient use.
Approach and implementation
The research work has been carried out through combined efforts regarding numerical modelling and experimental testing. The research has benefited from the composition of the project group with participation from five European universities and research institutes with complementary competences. The implementation has been partially disrupted by restrictions related to Covid-19, but thanks to good collaboration skills and the use of digital resources, the project has been carried out mostly according to original planning.
