Summary
The purpose of this study is to examine the mechanical properties of ACQ-treated glulam made from three hardwood lumbers. Two nondestructive methods, ultrasonic wave and tap tone method, were also used in this study. The results showed that the dynamic MOE and static MOE of lumbers decreased with increased ACQ preservative retention. ANOVA showed no significant difference in the MOE values of glulam between untreated and ACQ-treated group. However, it was also found that glulam made from red oak lumbers had the highest bending strength retention ratio. The shear strength of the glulam also showed similar results. Finally, no delaminating was found in all glulams after the specimens under soaked and boiled delamination tests.

Summary
At the beginning of the 20th century, a new wood manufacturing technology, i.e. cross-laminated timber (CLT), was started. In Taiwan, the manufacturing technology of CLT has just started recently. For the sake of safety, the information of stiffness and strength of the shear wall of the CLT are essential for structural designs. In this paper, by following the method B (ISO 16670 Protocol) of ASTM standard E2126-11, shear test of a real-scale CLT shear wall was performed. The measured shear modulus and cyclic test results of the CLT shear wall were reported in this paper. By using the three-dimensional digital image correlation technique, full-field deformation information of the CLT shear wall were obtained.
