The integration of partial joint penetration (PJP) groove welds within the AISC guidelines in IDEA StatiCa Connection addresses the specific requirements set by AISC for PJP butt welds, distinct from those for fillet welds.

IDEA StatiCa Connection offers PJP groove welds as an option for welds as per AISC 360 standards (2010, 2016, 2022 in table J2.5). Users can specify any weld that is edge-to-surface as a PJP weld in every manufacturing operation, e.g., weld or contact, fin plate, etc.

The checks are affected if the Base metal capacity at the fusion face is turned on in the Code setup. The Directional strength increase is not accounted for when using PJP welds.

For better reporting, special symbols for PJP welds and detailed formulas are provided, along with an adjusted analysis model that reflects accurate load-deformation curves and plastic stress redistribution.

In user-defined sections, a butt weld symbol with the correct effective throat thickness is displayed so that the produced drawings for reports are fully reliable.

The edge-to-rod type of PJP welding is not available and is converted to a full-penetration butt weld, which is not checked and is considered a part of the parent metal plate. Read about how to use rod member connections.

The ability to define PJP welds broadens the scope of design possibilities, allowing for more accurate and code-compliant projects.

Note: The Partial Joint Penetration (PJP) groove welds are available for AISC code only
