Introduction
GB/T 34744—2017 Standard Overview
| Performance indicators | Specimen size (unit: mm) |
|---|---|
| Tensile strength along the grain | 2500×90×40 |
| Compressive strength along the grain | 350×90×40 |
| Shear strength along the grain | 540 (between supports)×90×40 |
Implementation suggestions and practical application cases
In engineering practice, the determination of the performance design values of standard materials and tooth plate connections is crucial to the safety and reliability of light wood structures. The following is a typical application case:
In a light wood truss construction project, the design team selected appropriate specimen sizes and test methods based on this standard to ensure that the bearing capacity of the tooth plate connection met the design requirements. By using Q345 steel to make the tooth plate and strictly controlling the moisture content at 10%-20%, they successfully achieved the optimization of structural safety and economy.
