The through plate connection is a type of moment connection. 连接包括将两块板穿过 HSS 柱构件，同时连接到子构件的顶部和底部法兰. 它还使用剪切连接为整体连接提供额外的剪切强度, 使用的剪力连接通常是单板连接.
The through plate connection provides additional stability and rigidity in the actual connection joint allowing it to take more moment and shear load than other connections but it does have a relatively complex method of erection which would mean it can become a rather costly connection.
设计
Shown in the picture, the moment connection greatly increases in complexity when compared to shear connections. Normally only one type of moment connections exist in one structural space. This connection also then comes with increase calculations to ensure the connection itself is stable.
最佳实践
- Take extra precaution as the welds in the through plate connection can greatly decrease the strength of the HSS member
- As the HSS column is welded all around, ensure the thinner area of the plate does not suffer from shear tear out.
- When bolting on the top and bottom of the plate, be sure to leave enough space from the web to the bolts to minimize material damage
