Abstract

An innovative approach using laminated veneer lumber (LVL) hollow sections for temporary geotechnical slope stabilisation is being presented within this article. The use of circular laminated veneer lumber hollow sections as reinforcement elements in soil nailing walls demands load bearing elements, primarily loaded in tension, with a length up to 10 m. Thus finger-jointing was found to be an efficient method of a longitudinal load-carrying connection in combination with a minimized cross section reduction at the joint. This paper discusses the applicabiltiy of finger jointing on beech wood laminated veneer lumber hollow sections and presents the results of large scaled tensile under variaton of the joint arrangement.
