After an earthquake occurs, the working state of the X-shaped flexible steel sheet is checked, and the damaged standard unit can be removed in time and replaced quickly.

Description

Replaceable energy consumption pedestal based on X-shaped soft steel sheet
Technical Field
The invention relates to the field of shock absorption and energy consumption of buildings, equipment and cultural relics in collection of cultural institutions, in particular to a replaceable energy consumption pedestal based on X-shaped flexible steel sheets.
Background
Between the two major seismic zones in china, the eurasia seismic zone and the pacific seismic zone, is one of the most serious countries in the world suffering from seismic hazards. Historically, severe earthquakes of more than 6 grades have occurred many times in Yangtze river delta and Zhu river delta, and in the Bohai area of Kyoto hoop, a major earthquake of more than 7 grades occurs every 44 years on average in nearly 300 years. With the acceleration of the urbanization process, a large amount of national wealth is rapidly concentrated into cities and city cluster areas. More than one third of the established or proposed urban groups in China are located in areas where major earthquakes of more than 7 levels are likely to occur. The earthquake is that when the stratum of the earth crust is in a complex stress state and the action of the earth stress exceeds the ultimate strength of the stratum at a certain position along with the continuous change of the earth crust, the stratum can be suddenly broken and dislocated, so that the earthquake is caused, and is transmitted to the earth surface in the form of elastic waves, so that an object with certain mass near the earth surface generates inertia force, and when the self seismic capacity of the object for resisting the inertia action is insufficient, the object is damaged. When the excellent period of the local vibration is closer to the natural vibration period of the object, the damage of the object is more serious. The natural vibration period of the object can be obviously changed by arranging a certain vibration isolation device on the object, so that the excellent period of the earthquake is avoided, the inertia force acting on the object is obviously reduced, the damage of the object under the action of the earthquake is reduced, and the safety of the object under the earthquake is improved.
The other means for reducing the earthquake action is to adopt an energy consumption mode, and passively control the building by arranging a shock absorption support, a damper, an energy consumption support and the like. The control method allows the seismic energy to be transmitted to the building, but a specific energy consumption device (damper) is arranged in the upper building, most of the seismic energy which is originally consumed by the main building is transferred to the energy consumption device for dissipation, so that the damage of the building caused by plastic energy consumption is greatly reduced, and the building is effectively prevented from being seriously damaged and collapsed in the earthquake, therefore, the technology has good economic efficiency and application prospect. Compared with the seismic isolation technology, the energy-consuming and shock-absorbing technology is suitable for not only newly-built buildings but also seismic reinforcement of existing buildings, and has more obvious control effect on high-rise buildings, so that the energy-consuming and shock-absorbing technology is more widely applied to practical use. Although many progress has been made in the theoretical research of this aspect, the development and practical application of the corresponding energy-consuming and shock-absorbing device are still in the research stage.
