Test method for mechanical properties of bolted connection of wood structure

1 Scope

This standard specifies the test methods for the mechanical properties of the bolted connections of wooden structural materials and the compressive strength of bolt holes and pin grooves. This standard applies to connecting at least one wooden structural member and at least one other arbitrary material member through a single bolt fastener. The joint test pieces are connected with one-piece bolts, and the connection strength and stiffness are tested under the action of lateral load.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Structuralwoodandwood-basedmaterials It is also called structural wood material. It is wood or wood material that is used as a structural member to bear the load and can meet the requirements of engineering design. 3.2 Bolted joints At least one wooden structural member and at least one other arbitrary material (usually wooden structural material or (Steel plate or concrete) components are connected as a whole. 3.3 Single shear joints Single shear connection is the connection of two components connected by a single fastener, which only forms a single shear surface connection. 3.4 Double shear or multiple shear connection doubleshearormultishearjoints The double shear test is that two components are connected by a single fastener to form a connection between two or more shear surfaces. 3.5 Embedmentstrength The projection unit area of the bolt hole of the wooden structure bears the compression load of the bolt fastener. 3.6 Lateral load resistance lateralcapacitytoresistcompressiveortensileforces When a bolted fastener connects at least two components, the connecting part resists short-term lateral load (compression or tension) perpendicular to the axial direction of the fastener.
