4 I N T R O D U T I O N STRUTURAL PREANALYSIS TALES The calculation of KLH solid wood panels is carried out under the aspect of flexibly connected cross sections. The longitudinal layers are connected via flexible transverse layers. Therefore, bending caused by transverse forces (shear deformations of the transverse layers, rolling shear ) can no longer be disregarded. Dimensioning and structural design follow the Eurocode 5 (EN and EN ), taking into account the national standards set forth in ÖNORM and ÖNORM It should be pointed out that the national standards in various European countries differ from each other in some detailed aspects (e.g. different component safety coefficients for plywood board material). The product characteristics of the KLH solid wood panel required for structural design can be taken from the European Technical Approval (ETA06/0138). The static test for KLH solid wood panels must be made separately for each project, and the locally applicable standards and regulations have to be followed. Due care is also advised when comparing panel thicknesses of KLH elements with products by other manufacturers: due to different production processes, the plywood board products may well have different properties, e.g. as regards bending stiffness or shear strength. Please read the key values in the relevant product approvals and take into account the differences in the comparative calculation. For the calculation of plywood board elements, different calculation methods have been developed. The calculation can be carried out with the socalled shear analogy, the γmethod or even as a girder grid. In practical construction work, the γmethod is most often used. It is an approximation method developed for flexibly connected bending girders, but is also applicable for plywood boards. Instead of the flexibility of the connecting devices, the shear deformation of the transverse layers is taken into account. In practical construction work, this method is sufficiently exact. It is also included in the DIN 1052 and the Eurocode 5. For structural design, the net moments of inertia are calculated with a reduction coefficient and the resulting effective moments of inertia provide verification. 0 2

The fire resistance of the KLH solid wood panel can also be influenced by modifying the structures and can eventually be improved in relation to specific project requirements. 0 3
