I am happy to share with you next whitepaper: Direct Analysis Method
Designing for stability is a critical requirement for all steel structures, but implementing the latest stability analysis methods into engineering workflows can be challenging and have significant negative effects if done improperly. With the release of the AISC Specification for Structural Steel Buildings (AISC 360-05) in 2005, AISC introduced the Direct Analysis Method and imposed new requirements for stability analysis and design. These changes represent a fundamental shift in how engineers consider destabilizing effects, shifting the accounting of these effects from member capacity calculations to member demand (analysis) calculations. Utilizing the Direct Analysis Method results in greater accuracy, simplified member capacity calculations, and greater applicability to more types of structures.
