Abstract:
For further research on the improved Bouc-Wen model,a method of parametric identification was presented and the secondary development program was developed in this paper.And then the method was applied to the practices of 30 BRBs' experimental data.The changed trend,range and the average values of parameters of the improved Bouc-Wen model was presented for providing reference for applying improved Bouc-Wen model,and the value of the model parameters was suggested for application reference.Base on the finite element software ABAQUS,the improved Bouc-Wen model can be applied according to the UMAT.
