A kind of magnetorheological building foundation column

Abstract

The invention relates to a magnetorheological building base column and belongs to the technical field of earthquake-resistant fortification of buildings. This type of base column is a cylinder and is in the form of a discontinuous hollow body. The hollow cavity is filled with magnetorheological fluid; the inner wall of the base column is smooth and wrapped with coils, and the outer wall is a rough surface. The magnetorheological fluid in the base column will produce magnetorheological phenomena when the building encounters an earthquake. The energy-absorbing effect during the change of the magnetorheological fluid is used to absorb part of the vibration, shaking, etc. that will occur in the building due to the earthquake, thereby Reduce or delay the damage to buildings caused by earthquakes, thereby reducing damage to buildings and giving people in the buildings more time to escape. This type of foundation column is equipped with a seismic monitor to solve the problem of detecting earthquake intensity and earthquake duration; an angle sensor is installed in the building to detect the tilt of the building during an earthquake; the system detects the results of the earthquake monitor and angle sensor based on the Control the working status of the magnetorheological base columns in various directions.

Description

technical field [0001] The invention relates to a magneto-rheological building foundation column, which belongs to the technical field of building anti-seismic fortification. Background technique [0002] It can be said that human beings face the risk of being devastated by natural disasters every moment. Among various natural disasters, earthquake is one of the natural disasters with super destructive power. In my country, from the Tangshan Earthquake, Wenchuan Earthquake to Yushu Earthquake, the losses brought by the earthquake to victims, society and the country are immeasurable. From the perspective of the mechanism of earthquake damage, earthquakes transmit harmful energy to buildings in the form of waves, causing the buildings to "shake" up and down, left and right, and the buildings suffer damage to varying degrees. In an earthquake, the damage to the building is secondary, and what is more important is that the people in the building suffer casualties due to the sh...
