摘要：

Critical softening parameters for first-formed hinges at any location in a two-span beam are derived, and the relationship between positive load increments and softening parameters less than critical for midspan or interior support hinges are also determined. The effect of non-critical softening on the well known static collapse and shakedown loads for an elastic-plastic beam is found. It is shown that the combined effect of softening and residual moments (such as caused by differential settlements) on the static collapse and shakedown loads may be dramatic.
