Abstract

This chapter describes methods for checking structural stability, such as flexural, torsional, lateral torsional or local buckling of members or cross-section walls. It gives the procedures to define the design buckling resistance, which are, according to Eurocode 3, similar for all types of instability. The evaluation proceeds on four steps: a) determination of the critical elastic, Euler, load, b) calculation of the relative slenderness, c) evaluation of the reduction factor to buckling and d) determination of the buckling resistance by application of this factor to the yield load with due consideration of safety. Useful information is given at each step, for example for the Euler load which is calculated by differential equations or the energy method. In addition, recommendations and modelling possibilities for design by means of numerical non-linear analysis methods, as well as ways for the application of the very promising general method as defined by Eurocode 3 are given. The chapter ends with design methods for plate girders composed of walls susceptible to local buckling, with guidance for design of laced or battened built-up members and with verification procedures for composite girders consisting of steel beams and concrete flanges.
