Question

The design of the premature weld failure at the fin plate is governing for the design of a pinned beam connection with JOINTS.
What exactly does the design of the premature weld failure consider, and is it necessary to perform it in every case?


Answer:
This design or check is performed according to the ECCS recommendations.
For this, it is necessary that the weld is not governing for the ultimate limit state of the connection. The load-bearing capacity of the weld must therefore be > the load-bearing capacity of the fin plate.
If this check is not satisfied, you can either increase the weld thickness or reduce the thickness of the fin plate.
The design details show the minimum weld thickness for satisfying the requirement.
