Abstract Cross laminated timber (CLT) panels, which are used as load bearing
plates and shear panels in timber structures, can serve as roofs, walls and floors.
Since timber is construction material with relatively less stiffness, the design of
such structures is often driven by serviceability criteria, such as deflection and
vibration. Therefore, accurate vibration and elastic properties are vital for engineered CLT products. The objective of this research is to explore a method to
determine the natural frequencies of orthotropic wood plates efficiently and fast.
The method was developed based on vibration signal processing by wavelet to
acquire the effective sample… More >
