ABSTRACT:

In this paper, a new general formulation for stability design of steel columns, beams and beam-columns with variable geometry, loads and supports is proposed. The verification is based on buckling mode conform shape of the initial imperfection with an amplitude previously calibrated for the standard prismatic simply-supported columns and beams in Eurocode 3. It avoids the calibration of additional factors because it is applied as an interaction equation and the first and second order contributions to the longitudinal stress utilization are added for each cross-section along the member length. The paper summarizes the general formulation for design of steel members in a universal format covering any buckling mode. Several aspects regarding the member behaviour in the context of a specific buckling mode are discussed and finally, validation of the approach is carried out to show its consistency and accuracy.
