The directly welded moment connection is the weakest connection amongst all the connection but it is also the most commonly used of the moment connections in light weight frames.
Projeto
A double WT connection is considered to be one of the cheaper alternatives to the Soldar diretamente uma conexão em todas as direções cria um e Collared Plate Connection as it only requires extra bolting or welding for the WT sections to the HSS column.
Best Practices
- The double WT connection can be prone to high prying loads on the welds of the HSS column, therefore it is better to over design the welds use.
- The depth of the WT flange should not be wider than the flange of the child member.
- The web flange of the WT shape should not extend too long to prevent a higher moment load acting on the welds.
