Shakedown of Strain-Hardening Structures

Abstract: Elastic perfectly plastic theory predicts progressive permanent deformations of statically indeterminate structure with each cycle of variable repeated loading above the so-called shakedown load. Experimental evidence of this behavior, however, is contradictory. In an effort to explain some of the observed discrepancies, a theory of incremental deformations is developed which includes the effects of strain hardening of the material. On the basis of calculations, the importance of strain-hardening is assessed, and results of two earlier test programs are used to verify the validity of the approach. On the basis of comparison of analytical and experimental results, it is concluded that strain-hardening must be included for realistic prediction of the incremental deformations of steel structures.
