Stability Design of Steel Frames provides a summary of the behavior, analysis and design of structural steel members and frames with flexibly-jointed connections. The book presents the theory and design of structural stability and includes extensions of computer-based analyses for individual members in space with imperfections. It also shows how connection flexibility influences the behavior and design of steel frames and how designers must consider this in a limit-state analysis and design procedure. The clearly written text and extensive bibliography make this a practical book for advanced students, researchers and professionals in civil and structural engineering, as well as a useful supplement to traditional books on the theory and design of structural stability.

1.1 Introduction

Beam-columns are structural members subjected to combined axial forces and bending moments. The bending moments that are present in a beam-column consist of two types: primary bending moments which arise from moments applied or induced at the ends of the member and/or moments from transverse loadings on the member; secondary bending moments which arise as a result of the axial force acting through the lateral displacement of the member. The so-called P−δ moments are moments caused by the axial force acting through the lateral displacement of the member relative to its chord (Fig. 1.1a), whereas the P−Δ moments are moments caused by the axial force acting through the relative lateral displacement of the two ends of the member (Fig. 1.1b).

Secondary moments generally produce detrimental effects to slender compression members and so they must be accounted for in design. The nature and the manner in which these secondary moments are incorporated in the analysis and design of structural members in frames will be addressed in this and the following chapters.

Beam-columns can be considered as the basic element of a structural frame. Beams and columns are special cases of beam-columns. In the case of beams, the effect of axial force on the primary bending moments is negligible, but in the case of beam-columns this effe...
