Abstract

The invention discloses a method for using a modular steel hysteresis damper, which relates to the method for using the steel hysteresis damper and solves the problem that power consumption function of the damper is not showed completely due to the arrangement mode of the current shock absorption and power consumption damper. Mounting position of the modular steel hysteresis damper is determined; dampers are arranged on all the floors layer by layer up from the half height of a shear wall, and the planes on all the layers are ensured to be arranged symmetrically; an integral structure power model is built by using elastic-plastic analysis software, and specific quantity and type numbers of the modular steel hysteresis dampers arranged on each connecting beam are determined; yield shear force of the modular steel hysteresis damper arranged on a cutoff position of each connecting beam is between shear force in small seism and middle seism of the connecting beam; and, after the selected connecting beam is cut off from the middle part, space scale of the mounted modular steel hysteresis damper is matched with that of an cutoff opening of the connecting beam, thereby ensuring that the geometrical shape of the connecting beam is unchanged. The power consumption function of the damper is maximally showed due to the arrangement mode of the damper provided by the invention, so that the modular steel hysteresis damper is absolutely suitable for use in seismic design.

Description

technical field [0001] The invention relates to a method for using a steel hysteresis damper. Background technique [0002] The building structure shakes under the action of an earthquake. If the shaking is too large, the structure will be damaged or even collapsed, resulting in catastrophic consequences such as casualties and property losses. Dampers are energy consuming devices designed to dissipate this harmful energy that causes building structures to sway. According to the relationship between force and deformation, materials can be divided into elastic materials and plastic materials. The so-called elasticity refers to the corresponding deformation of the material after the force is applied, and the deformation disappears after the force is removed. For example, the rubber band is the representative of the elastic material; , a small increase in force produces a large deformation, and the deformation cannot completely disappear after the force is removed. This charac...
