Mechanical Properties of Innovative Multifunctional Cross Laminated Timber

This paper deals with wall elements from massive timber, which are modified for thermal activation – multifunctional cross laminated timber (multifunctional CLT). This wood product is currently developed towards maturity for application, by determining e.g. the mechanical properties. The multifunctional CLT elements feature channels in which conditioned air circulates, reducing the cross-sectional area. In this paper we investigate e.g. the compression strength and stiffness, the buckling load, the in-plane shear strength and stiffness and the torsional stiffness properties of multifunctional CLT by means of extensive series of mechanical testing. In addition, the deformation behavior of multifunctional CLT under moisture changes as well as possible cracking in the front layers will be analyzed.     «
