Welds W1 and W2 are sufficient when analyzed with a weld coefficient (ex. 0.85) but will fail with a coefficient of 1. Either way the weld class appears to be represented wrongfully in the report (ex. 80 for both weld coefficients).
Example:
Example values may not match your scenario. This is just an example.
As you can be see when the test category is set to 3 (so the joint coefficient changes to 0.85), the Pmax is the same and the cumulative damage stays below 1, while it is 1.5 when the joint coefficient is 1.
Answer:
To answer the specific scenario above, as per EN 13445-3 17.6, the joint efficiency z is used to calculate h, which is used to calculate Delta Sigma
There is no impact on Pmax.
There is no impact on Pmax.
