A comparison of stability design requirements: A work in progress of SSRC task committees on systems and extreme loads and the ASCE/SEI methods of design committee

Varied analytical approaches, philosophies of design and standards have created a complex landscape for designers of steel-framed lateral systems subjected to a combination of static, dynamic, blast and/or temperature loads. This session will present the progress of a combined effort of the ASCE/SEI Methods of Design Committee and the SSRC Task Groups on System Stability and Extreme Loads. The project will develop a comprehensive case study to elucidate the differences in analysis and design philosophies for stability assessment of frames by developing independent designs of the same framing system using different standards and design threats. The resulting designs will be both compared and contrasted for analysis rigor, controlling limit states of the resulting designs and stability assessment approaches. The case studies will involve input of practitioners and academics.
