Building structure model seismic absorption and isolation technology demonstrator

Abstract

The invention discloses a building structure model seismic absorption and isolation technology demonstrator. The building structure model seismic absorption and isolation technology demonstrator comprises a building structure model, an upper seat plate (8) and a seismic simulation motion platform. The building structure model seismic absorption and isolation technology demonstrator is characterized in that one side of the upper seat plate (8) is fixedly connected with the building structure model, the other side of the upper seat plate (8) is fixedly connected with the seismic simulation motion platform, and two sides, which are connected with the seismic simulation motion platform, of the upper seat plate (8) are parallelly and fixedly provided with sliding blocks which are provided with sliding grooves; the seismic simulation motion platform comprises an engine base, a base shaking and driving device and a base, the engine base is provided with guide rails which are fitted with the sliding grooves, the base shaking and driving device comprises a turbine motor speed reducer (1), an output shaft (9), a flange sleeve (10), a base plate (11), a connection plate (12), a coupling (7) and an eccentric coupling (13), the output shaft (9) is in transmission connection, and the coupling (7) is internally provided with an eccentric sleeve (14). The invention aims at providing the building structure model seismic absorption and isolation technology demonstrator which is simple in structure and low in cost and is capable of directly showing all kinds of different anti-seismic phenomena showed by all kinds of seismic absorption buildings under the action of seismic waves.

Description

technical field [0001] The invention belongs to a building structure demonstrator, in particular to a building structure model shock-absorbing and isolation technology demonstrator. Background technique [0002] Earthquakes, also known as ground motions and ground vibrations, are shock waves generated by sudden ruptures in the interior of the earth, and are a natural phenomenon that often occurs on the earth. Due to the rapid vibration of the earth's surface caused by the movement of the earth's crust, the vibration caused by the rapid release of energy from the earth's crust produces seismic waves during this period. It is also a special form of crustal movement. Earthquake is a geological disaster with strong suddenness, severe instantaneous destructiveness, unpredictable secondary disasters, profound social impact, casualties and property loss. [0003] When an earthquake occurs, the most basic phenomenon is the continuous vibration of the ground, and the main feature i...
