What does structural integrity imply according to AWS D1.1?

Structural integrity, as defined by the AWS D1.1 code, implies that welded components must fulfill safety, durability, and performance standards to ensure they can adequately support the intended loads and operations throughout their service life. This concept is crucial because structural integrity directly relates to the safety and reliability of structures. The code sets specific requirements and guidelines for the design, fabrication, and inspection of welded connections to maintain structural integrity, ensuring that these components can withstand not only static loads but also dynamic influences and environmental factors.

In this context, safety encompasses not just the physical stability of the structure but also the prevention of failure that could potentially harm people or property. Durability relates to the material's ability to resist wear and damage over time, while performance standards involve the functional characteristics required for the structure to fulfill its intended purpose effectively. By adhering to these standards, engineers and contractors can ensure that their welded structures will perform as expected under designated conditions, thus safeguarding against unexpected failures and extending the life of the structure.
