For a single-lap sheet splice, what is the minimum overlap required when using a double row of 1/8 inch rivets?

The minimum overlap required for a single-lap sheet splice using a double row of 1/8 inch rivets is 13/16 inch. This specification is essential for ensuring adequate strength and load distribution across the splice joint.

The overlap provides enough area for the rivets to effectively transfer loads between the two sheets, thus preventing a failure mode known as pinch loading. The size of the rivets and the number of rows directly influence the required overlap to ensure that the riveted joint can handle the anticipated stresses without compromising the integrity of the structure.

In practical terms, the 13/16 inch minimum overlap for a double row of 1/8 inch rivets is also grounded in standard engineering practices and design guidelines, which take into account variables such as material thickness, type of load being applied, and safety factors pertinent to aviation standards. The other values, while they might build in excess margin, do not reflect the standard engineering practices that have established the specific overlap dimensions for riveted joints.
