Structural Joints In Glulam

Joints in large glulam timber frames contribute significantly to the cost of the assembled structural system. Because of the demands of aesthetics and the continuing need to achieve structural efficiency and cost competitiveness, timber jointing methods are steadily evolving. Many jointing options are currently available to the designer. Appropriate choice of joint type will ensure an efficient load transfer element together with ease of manufacture and assembly. This paper presents a New Zealand perspective on jointing solutions with illustrations from successful projects constructed locally and overseas with varying environmental conditions and code requirements. The advantages and disadvantages, of each system will be discussed
