A Development of an Evaluation System for Finger-jointed Laminae with Starved Joints by Acoustic Emission

摘要：

Introduction Recently, many wooden buildings made of glulam timbers have been constructed in Japan. To guarantee the strength properties of these timbers, a high level of quality control is needed. The laminae that comprise glulam timber are generally finger-jointed. However, laminae with starved joints in the finger-joint arc occasionally found in the manufacture of glu|am timbers, and greatly decrease the timbers strength. Therefore, for the manufacture of glulam timbers with good strength properties, the evaluation of finger-joint properties after finger-jointing is important, and the method is hoped to be simple and non-destructive.
