The through plate connection is a type of moment connection. A conexão consiste em passar duas placas através do membro da coluna HSS enquanto é conectada aos flanges superior e inferior dos membros filhos. Ele também usa conexões de cisalhamento para fornecer resistência extra de cisalhamento para a conexão geral, the shear connection used is normally single plate connections.

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.

Projeto

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.

Best Practices

• 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
