The removal of the unbalance forces related with the non-mass degree of freedom, generated between steps of integration on flexible frames, is presented for the sub-structuring hybrid scheme. Four different predictors of the specimen response, Elastic model, two-component Bili near model, Multi-Spring model, and Neural Network model, are evaluated in order to eliminate and reduce the unbalance forces under constant axial load. A controlled variation of the moment gradient are considered for the first time in this kind of simulation. Box-shaped sections 100 x 100 x 6 are considered as test specimen for the special conditions of the test setup and the required transformations are presented. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
