Du Sentian (Jilin University of Technology,Changchen,130022) Xu Bingye (Tsinghua University,Beijing,100084) Dong Yunfeng (JUT)  
This paper is based on piecewise linear yield surface and discretization of structure.Under the Condi-tion of allowing for inertia forcc,damping force and second-order geometric effect,the two generalizeddynamic shakedown theorems are given for the shakedown analysis of structure.
