Study on Joint Ductility Assurance Design of Glued Laminated Timber Frame with Tensile Bolts Type Joint

Abstract

For the purpose of promotion of the mid-rise timber building, we tried to design glued laminated timber frame structures of semi-fireproof construction, and designed the structural and fire resistance specifications. In this paper, it was confirmed in the experiment structural performance of tensile-bolted joints designed based on the trial design. For tensile-bolted joint, we examined the maximum strength of the bolt to the fracture toughness of the failure mode type. The Bolts were designed with the upper limit of 5% of the yield stress and the ultimate strength. By the experiment, it was confirmed experimentally that the validity of the mechanism assurance design of brittle failure mode prevention.
