ENHANCED PERFORMANCE OF LONGITUDINALLY POST-TENSIONED LONG-SPAN LVL BEAMS

摘要

The scope of this paper is to highlight the advantages of using longitudinally post-tensioning for long-span timber beams compared to traditional LVL solutions. Post-tensioning was started by Fressynet with concrete members with the intent to improve the overall structural performance to external loads when long span beams and bridges are targeted. The same technology relying on unbonded post-tensioned tendons/bars can be easily applied to timber.
