Abstract
The invention discloses a method for damping and energy dissipation of a high-rise housing energy dissipation wall, and a device thereof. The method comprises: firstly, manufacturing a lower energy dissipation wall on a lower layer floor beam of a high-rise housing, manufacturing an upper energy dissipation wall on an upper layer floor beam, pre-embedding built-in fittings in the lower energy dissipation wall and the upper energy dissipation wall, and manufacturing an energy dissipation key which can be connected with the built-in fitting in the lower energy dissipation wall and the built-in fitting in the upper energy dissipation wall between the lower energy dissipation wall and the upper energy dissipation wall. The upper energy dissipation wall and the lower energy dissipation wall transmit energy generated by earthquake to the energy dissipation key in time, so the energy dissipation key rapidly enters a yield situation, and earthquake energy is effectively dissipated in hysteresis, so as to reduce reaction of a main body structure under earthquake action. The method and the device improve earthquake fortification intensity of an ultra high-rise residential building, ensure the building not to collapse under great earthquake action and ensure personnel safety, and effectively protect building structure and indoor interior trim, and improve anti-seismic safety level of the building in design working life, so loss of the building in earthquake is reduced to minimum.
