Behaviour of portal and strut types of beam-columns

Abstract A numerical procedure combining the finite segment method with the influence coefficient method has been developed for the cyclic inelastic analysis of steel tubular beam-columns. In this paper, extensive numerical studies of the behaviour of portal and strut-types of beam-columns under monotonic and cyclic loadings are made, using the computer model developed. These studies confirmed the suitability of the numerical procedure proposed. Comparisons have also been made with the results of tests on actual members, providing the needed confirmation of the validity of the method.
