Bolt Joints of Kerto-LVL Reinforced with Nail Plates

摘要

Joints suitable for building site assembly of Kerto-LVL structures have beendeveloped. The design methods for bolt joints reinforced with nail plates, used in both solid timber and Kerto-LVL structures, have been determined earlier based on testing of altogether 207 nail plate reinforced joints in short and long term loading. It was found that a joint reinforced with ordinary nail plates has 2.3 fold capacity compared with a normal bolt joint. Use of special nail plates without punched nails around the bolt area makes the joint even more rigid and increases the capacity of the joint because the punched holes do not decrease the embedding stress area of the plate.
