Bending Properties of Cross Laminated Timber (CLT) with a 45° Alternating Layer Configuration

摘要: Bending tests were conducted with cross laminated timber (CLT) panels made using an alternating layer arrangement. Boards of Norway spruce used to manufacture five-layer on industrial CLT production line. In total, 20 samples tested, consisting two configurations 10 each type: transverse layers at 45° and the conventional 90° Sample dimensions 95 mm × 590 2000 mm. The tested by four point bending in main load-carrying direction a flatwise panel layup. results indicated that strength increased 35% for elements assembled comparison layers. Improved mechanical load bearing properties could lead larger span length less material.
