| Abstract: | This paper presents a new structural system for reducing earthquake response.A kind of energy dissipation control system is placed on the main structure.When the structure reaches the maximum displacement point and begins to move in the opposite direction in one side,the control devices are opened and the seismic energy absorbed b the structural members with the energy dissipation devices is dropped.Then the control devices are closed and the members continue to absorb the seismic energy.When the structure reaches the maximum displacement and begins to move in the opposite direction in another side,the control devices are opened and the absorbed energy is dropped again.The structure can drop seismic energy two times in one natural period,so the structural seismic response can be reduced greatly. The basic theory and mathematical model of the energy dissipation system for reducing the earthquake response and the seismic analysis of this kind of structure are given in this paper. |
