| Abstract | The improved compression-free device with a single cam-grip mechanism to eliminate the error of the relative motion of the steel cams proposed in this study, the compression-free device mechanism, was designed to disengage under compressive loading and grip under tensile loading. The sub-assembly test was done with lateral reversed-cyclic loads to evaluate the compression-free device that was tested through the compression-free energy dissipative brace. The experiment results show that this improvement can get rid of the error caused by the relative movement of the steel cams and make the hysteresis behavior stable and repeatable under lateral loads. Also, the results of the experiments are compared to the original CFD mechanism used to perform the CFB work. |
