Dynamic Response Mechanics of 45 Degree Angled Layered Cross-Laminated Timber

Abstract

This research is directed on dynamic properties of cross-laminated timber (CLT) panels constructed with alternate angled layers. All panels were manufactured using a modified industrial CLT production line, and the timber lamellas were glued and pressed together in a single step procedure to form the CLT panels. The paper also presents that the CLT with 45° configuration can be industrially produced at the same material quantity in comparison with standard production. Tests showed that the 45°-configured panels had 30% higher compression stiffness and 15% higher compression strength when compared to the 90° configuration. The results showed that the achieved mechanical properties of the new configuration can be utilized as a suitable construction material.
