Structural Drawing — In modern steelwork, riveting is rarely used; bolted (high-strength) and welded connections dominate, making the statement that riveting is seldom used essentially correct.

Introduction / Context:
Historically, rivets were common in steel bridges and buildings. Advances in high-strength bolts and welding technology have largely displaced riveting due to ease of installation, inspection, and performance characteristics, so riveting is now seldom specified in new work.

Given Data / Assumptions:

• Current codes and practices favor bolts and welds.
• Riveting requires specialized labor and equipment.
• Existing riveted structures may still be maintained.

Concept / Approach:
High-strength bolts provide controlled pretension, are replaceable, and simplify field work. Welding enables continuous load paths and sealed joints. Riveting persists mainly in restoration projects where historic authenticity is required.

Step-by-Step Solution:
1) Evaluate connection requirements (shear, tension, moment).2) Select bolts or welds per modern detailing standards.3) Reserve rivets for heritage work if mandated.4) Document inspection and QA procedures accordingly.

Verification / Alternative check:
Contemporary specifications and fabricator capabilities lists rarely include riveting for new projects, confirming its limited use.

Why Other Options Are Wrong:
Mandating rivets for trusses or alongside welding contradicts efficient practice; using rivets to “mark orientation” is nonsensical.

Common Pitfalls:
Confusing maintenance of riveted heritage structures with new-construction methods.

Final Answer:
Correct
