In comparison to traditional LTF walls, the novelty aspect is the use of cross-laminated timber (CLT) beams and studs instead of solid timber elements. Thanks to this ‘hybrid’ approach, this new system combines some peculiar aspects of LTF structures (such as the limited weight and the high dissipative behaviour) with the potentials of CLT. Moreover, the use of CLT elements limits the issues due to the compressive deformations on bottom beams and permits to employ some innovative connections with high mechanical properties. Cyclic shear tests are carried out on two configurations of interest, assembled by considering different layouts of the load-bearing elements. Test results are compared to the experimental data obtained on similar LTF systems and differences are critically discussed.

The wall modulus, in this paper referred to as Hybrid Timber Frame (HTF) wall system, is an evolution of the traditional Light-Frame Timber (LFT) structural systems and combines the advantages and some peculiar aspects of lightweight structures to the potentialities of Cross-Laminated Timber (CLT) panels. This hybrid approach makes the HTF structural system suitable for the production of light and high-performing wall moduli, allowing an advanced prefabrication process, fast assembling procedures and a simple disassembly. The paper provides a description of the HTF wall system following a multidisciplinary approach. Particular attention is paid to the mechanical and geometrical characterisation of three HTF wall moduli, used to assemble different housing units. The structural design is carried out by considering severe loading conditions (which inc...

This is especially evident in the area of building construction where the use of components with optimized thermal transmittance can contribute to energy savings. A research project was carried out to develop new wooden profiles for window production. The project focused on reducing thermal transmittance using glulam oak elements for windows frame instead of solid wood, and verifying the feasibility to use other hardwood species not previously considered. Specific experimental equipment and procedures were used to measure the thermal performance of 20 different samples of glulam elements made from oak, other hardwood timbers (okoumé, fromager, poplar, alder), different materials (cork, rubber, MDF), and with inner layers containing air pockets of different sizes. The combination of oak and alder showed the best performances. After several FEM simulations, the project team developed an adjustment of t...

This demonstration shows that it is possible to use wood, for contemporary prefabricated connected, sustainable buildings.
