Weld size differences between EC and AISC (CISC) codes

There is a difference between weld size definitions in welding operations when you design according to EC or AISC (CISC) codes. Please remember it while making a model of a joint in IDEA StatiCa.

Under EN, the weld size is defined as the parameter a, which is the weld throat thickness.

Under AISC (CISC), the weld size is defined as the parameter z, which is the weld leg size.

You can simply calculate a from z and vice versa using the Pythagorean Theorem.
