Adsorption Properties and Structural Features of Alkali Treated Wood
alkali treatment contraction structural features microfibrils
2009/3/6
In order to investigate the influence of alkali treatment on structural features and on hygroscopic properties, weight and dimensions were measured after wood samples (Picea jezoensis Carr.) were trea...
Development of a Shear Testing Method for Full-sized Structural Lumber
shear strength testing method full-sized structural lumber sugi
2009/3/6
An asymmetric four-point-bending type shear test was developed to evaluate the shear strength of full-sized structural lumber. Medium dimension glulam made of sugi (Cryptomeria japonica D. Don) from M...
