Study on a Passive Control System of Structural Seismic Responses

The intention of this paper was to design an effective and feasible method to control the seismic responses of structures within a safe range. Through the Shape Memory Alloy, this is achieved. In this paper, several tests were made to find out the impacts that temperature and max strain values may make on Shape Memory Alloy pseudo-elasticity effects, then, according to the experiment result, 2 kinds of Shape Memory Alloy dampers are designed and their mechanical performances are tested, after that, a passive seismic response control system is design using the dampers, at last, the control system was installed on the model of an actual high-rise structure, and the control effect was tested and proved to be well.
