Unified Stability Design of Steel Structures Using Nonprismatic and Curved Members

This paper provides an overview of several research developments I have been privileged to be involved with during my 30+ years of engagement with colleagues within the Structural Stability Research Council, AISC, MBMA, AISI, FHWA, and AASHTO. Emphasis is given to key concepts and procedures captured within the recently-published AISC/MBMA Design Guide 25 Second Edition, Frame Design Using Nonprismatic Members, the applicability of these concepts and procedures to the design of arches, and related concepts and methods implemented in the AASHTO LRFD Specifications for the unified design of straight and horizontally curved bridge I-girders.
