A parametric finite element analysis is performed to study the possible trade-offs in terms of geometric and material properties of the solid timber panel in order to maintain a high shear stiffness. The parameters that are studied are: 1) the angle of the inclined board layers (DLT), 2) the timber board thickness, 3) the timber board width, and 4) the quality of the timber material.
The results from the analyses show that there can be significant gains in shear stiffness by using inclined boards as in diagonally laminated timber (DLT) panels compared to more traditional cross laminated (CLT) panels. The trade-off is that it can be possible to use lower grades of material, thinner reinforcement layers and boards with lesser width.
