oa Civil Engineering = Siviele Ingenieurswese - A Newmark-type approach to the analysis of elastic beam buckling



The paper presents a straightforward yet versatile approach to the analysis of elastic beam buckling. The proposed method is essentially an adaptation and extension of that proposed by Newmark for the buckling of axially-loaded columns. This makes for ease of programming and facilitates the analysis of refined numerical models. The analytical procedure is demonstrated by means of model calculations, and its validity is attested by comparisons with the results of previously published buckling analyses.
