ABSTRACT

This chapter presents a succinct encapsulation of various analysis approaches for frame design ranging from simplified member-by-member design approach to more sophisticated computer-based analysis/design approach. It provides a smooth transition from the current state-of-the-art knowledge on the analysis and design of steel frames to upcoming new technology and developments in engineering practice. The chapter addresses trends and directions of advanced analysis in steel building design. It reviews the background behind the development of the current American Institute of Steel Construction (AISC)-Load and Resistance Factor Design (LRFD) beam-column interaction equations, and discusses the use of effective length factors for beam-column design. The chapter also reviews the recent work on the design of semi-rigid frames based on the extension of the current AISC-LRFD B1/B2 approach. It also discusses the general issues pertinent to verification and benchmarking of second-order inelastic analyses for use as advanced analysis, and provides a conclusion and directions for further research.
