How does the AWS D1.1 code address seismic design?

The AWS D1.1 code incorporates specific performance requirements for seismic design to ensure the integrity and safety of structures during seismic events. This approach is essential because structures must be able to withstand the forces generated by earthquakes. The code outlines criteria for materials, design methods, and welding techniques that are necessary to help ensure that welded connections can endure seismic stresses without failure.

This performance-oriented focus acknowledges the complexities of seismic forces and emphasizes the importance of designing welds and connections to maintain overall structural stability and resilience under such conditions. By establishing these requirements, AWS D1.1 plays a critical role in enhancing the safety and reliability of welded structures in seismically active regions.
