Fence type shock insulation structure and design method thereof

Abstract

The invention discloses a fence type shock insulation structure and a design method thereof, and belongs to the technical field of shock insulation structures. The fence type shock insulation structure comprises a plurality of anti-seismic units, and the multiple anti-seismic units are arranged and distributed on the outer side of a protected building with the protected building as the circle center to form a circular shock insulation structure. The bottom surface of an anti-seismic unit is fixed with a foundation; the anti-seismic unit is of a block-shaped structure with a rectangular section. According to the design method of the fence type shock insulation structure, the shock insulation structure and the foundation are modeled and simulated through a finite element method. A parametric modeling method is adopted when the anti-seismic units and the circular arrangement of the anti-seismic units are designed and calculated, and simulation results of different geometric dimensions and different materials can be obtained only by scanning designed parameters. According to the fence type shock insulation structure and the design method thereof, the arrangement mode is simple and easy to implement, and the problems that a traditional anti-seismic structure is complex in design and large in installation difficulty are solved; the problem that according to a traditional anti-seismic scheme, the anti-seismic performance of an existing building cannot be upgraded under the condition that the structure of the existing building is not changed at all is solved.

technical field

[0001] The invention belongs to the technical field of shock-isolation structures, and in particular relates to a fence-type shock-isolation structure and a design method thereof. Background technique

[0002] Earthquakes are frequent natural disasters that are sudden and unpredictable. Strong earthquakes will cause strong vibrations on the ground, directly or indirectly causing damage to society and nature. In production practice, earthquake disasters are often the greatest potential threat to damage to surface structures such as houses and buildings. When the seismic wave generated during an earthquake reaches the surface interface, it will form a seismic surface wave (Rayleigh wave). The surface wave causes the vibration of the building structure, which is the main reason for the failure or even destruction of the ground structure. Based on this, it is an important issue to carry out vibration isolation for the area where the building structure is locate...
