| Abstract | The improvement on compression free energy dissipative brace mechanisms to eliminate low initial stiffness is proposed in this study, The CFD brace mechanisms were designed to release under compression loading and clamp under tensile loading. The sub-assemblage test was conducted under difference cyclic loading to evaluate the performance of CFD brace improvement. The results indicate that this improvement can eliminate low initial stiffness and present steady and repeated hysteresis behavior under cyclic loading. Furthermore, the Park& Ang model was adopted to evaluate and predict the damage index under cyclic loading at failure point of CFD brace, the results of this model indicate that this model match with the experiment results; thus, it can be concluded that the Park& And model can be used to predict and investigate the damage index for CFD brace. |
