Plastic Design in High Strength Steel. Bracing Requirements for Inelastic Steel Beams

摘要

The question of bracing design is examined and seen to depend on the fulfillment of three criteria: axial strength, axial stiffness, and bending strength and stiffness with respect to the ZZ axis of the beam. Equations are presented which allow each of these criteria to be defined. Their application is seen to be simple and in accord with available test results. The derivations given have been coupled with previous work on the deformation capacity of steel beams under uniform moment, and the resulting, solutions are the first available for plastically deformed beams.
