Description

Shock absorption device arranged between shock insulation seams and mounting method
Technical Field
The invention relates to the field of building shock absorption and isolation, in particular to a shock absorption device capable of consuming seismic energy in an earthquake, and belongs to the engineering structure shock absorption and isolation technology in civil engineering.
Background
China is one of countries with frequent earthquakes in the world, a plurality of earthquakes historically bring huge losses to lives and properties of people, and the earthquake-resistant performance of buildings is closely related to the safety of lives and properties of people, so that the earthquake-resistant research of the buildings is of great importance. The building structure is regular, so that the earthquake-resistant joint is arranged to be beneficial to earthquake resistance of the structure, and the foundation can not be broken. The earthquake-proof structure is arranged to divide a large building into smaller parts to form relatively independent earthquake-proof units, so that damage caused by the fact that the whole earthquake of the building is not coordinated is avoided. In the earthquake process, buildings on two sides of an earthquake-proof seam arranged on a building structure are collided, and the building structure is also damaged greatly, so that the life and property safety of people is harmed. These effects are particularly pronounced under the action of major earthquakes.
The traditional earthquake-proof design method achieves the effect of resisting earthquake action by improving the strength and the deformation capacity of structural members, namely, the section size and the reinforcing bars of the structural members are increased, but the method not only increases the materials used by the building, but also increases the rigidity of the building to a certain extent, the earthquake action on the structure is also increased, further the energy absorbed by the building is increased, the dissipation of the energy is realized by the way that the structure generates nonlinear deformation such as cracks and damages, and the structure is seriously damaged or even collapsed as a result.
With the development of related research on building structures, deformation joints are often arranged according to the requirements of seismic fortification of buildings to reduce or eliminate the influence of earthquake action on the adjacent building structures. The deformation joint can be divided into an expansion joint, a settlement joint and an anti-seismic joint. There are many buildings that take these three types of seams into account, so-called "three-in-one" seams; the seam width is processed according to the width of the anti-seismic seam, and the foundation is broken according to the settlement seam. Therefore, the damping device capable of being arranged between the deformation joints has a good design prospect on the seismic resistance between structures. In recent years, many students find that a building can not be simply designed for earthquake resistance, especially in a middle-low-rise building, when an earthquake occurs, a structural member cannot simultaneously take effects of strength and deformation into consideration, so that a new thought and a new structure are provided for absorbing a part of earthquake energy. The function of the seismic isolation structure for effectively isolating horizontal earthquakes is not fully researched on the function of deformation joints among structures.
