【Abstract】 A finite element model was established by using ANSYS. The eigenvalue buckling analysis of new buckling-restrained brace was carried out. The calculation results include the first 2-order eigenvalue buckling modes and the buckling loads. The results show that the analysis with ANSYS is precise, the model and calculating method is rational, new buckling-restrained brace is a reliable and stable structure energy-dissipation system.更多还原
