Type of riveted joint pattern\nWhen rivets in adjacent rows are directly opposite each other, how is the riveted joint described?

Introduction / Context:
Riveted joints are classified by the relative position of rivets in successive rows. Correct terminology is essential for fabrication drawings and strength calculations.

Given Data / Assumptions:

• Multiple rows of rivets connecting plates.
• Interest is only in the positional pattern of rivets.

Concept / Approach:
In chain riveting, rivets in adjacent rows are aligned directly opposite, forming straight transverse lines. In zig-zag riveting, rivets in one row are staggered relative to the next, forming a zig-zag path.

Step-by-Step Identification:
Observe the rows: if rivets line up across rows, it is chain riveting.If rivets alternate positions between rows, it is zig-zag (staggered).

Verification / Alternative check:
Handbooks and codes use these standard definitions for layout and pitch computations.

Why Other Options Are Wrong:
“Zig-zag” implies stagger; “Diamond” is a special pattern; “Staggered lap” is a descriptive phrase, not the standard name; “Cruciform” refers to a type of joint configuration, not this pattern.

Common Pitfalls:
Confusing chain and zig-zag when pitches are unequal; misreading drawings.

Final Answer:
Chain riveted
