摘要：

This study aims to propose the fracture load formula of tensile bolt fixed portion of glued laminated timber frame with tensile bolt joint from the relationship between shear-length, maximum load and failure mode. The destruction tests of tensile bolt fixed portion of the same grade glued laminated timber were carried out. The knowledges from these experiments are as shown below? 1. When the shear length is up to 300mm, shear failure is the major failure mode, and the fracture load is increased in proportion to the shear length. When the shear length is over 300mm, compression failure is the major failure mode, and the fracture load is about the same regardless of the length. 2. The fracture load formula of tensile bolt fixed portion of glued laminated timber frame with tensile bolt joint was proposed. About the range of shear length from 120mm to 420mm, it is confirmed that the proposed formula can predict the fracture load to a safety side. © 2017 Architectural Institute of Japan.
