Embodiment 1

[0043] figure 1 It is a schematic flowchart of a building safety assessment method provided by Embodiment 1 of the present invention. This embodiment is applicable to monitoring the structural health of buildings. like figure 1 As shown, the building safety assessment method provided by Embodiment 1 of the present invention includes:

[0044] S110. Acquire seismic background noise data of the building to be measured.

[0045] Specifically, the building to be tested refers to a building that requires a safety assessment. Generally, performing a safety assessment on a building is to perform a health inspection on the building, that is, to determine whether the structure of the building is normal or safe. The seismic background noise data refers to the background noise data measured by the seismograph installed inside the building to be tested.

[0046] S120. Perform clock drift correction on the seismic background noise data to obtain correction data.

[0047] Specifically, ...

Embodiment 2

[0054] figure 2 It is a schematic flowchart of a building safety assessment method provided by Embodiment 2 of the present invention, and this embodiment is a further refinement of the foregoing embodiments. like figure 2 As shown, the building safety assessment method provided by the embodiment of the present invention includes:

[0055] S210. Obtain seismic background noise data within a preset observation period through a dense array seismometer set in the building to be measured.

[0056]In this embodiment, the building to be tested is a super high-rise building, such as Shanghai Tower. If a seismometer is placed on each floor of the building to be tested, then all the seismometers in the building to be tested form a dense array. For example, if a seismometer is placed on each floor of the Shanghai Tower, a total of 126 seismometers are deployed, and the seismometers are placed at the same position on each floor, then the seismometers in the Shanghai Tower form a vert...

Embodiment 3

[0067] image 3 It is a schematic flow chart of a building safety assessment method provided by Embodiment 3 of the present invention. This embodiment is a further optimization of the foregoing embodiments. like image 3 As shown, the building safety assessment method provided by the embodiment of the present invention includes:

[0068] S310. Obtain seismic background noise data within a preset observation period through a dense array seismometer set in the building to be measured.

[0069] S320. Perform clock drift correction on the seismic background noise data through seismic cross-correlation interferometry technology to obtain correction data.

[0070] S330. Determine the velocity disturbance of the building to be tested according to the calibration data.

[0071] Specifically, the velocity disturbance refers to the variation range of the velocity of the building to be measured in response to external excitation. In this embodiment, the external excitation is the nois...

Abstract

The embodiment of the invention discloses a building safety assessment method and device, equipment and a storage medium. The method comprises the steps of acquiring seismic background noise data of ato-be-tested building; performing clock drift correction on the seismic background noise data to obtain correction data; determining the natural vibration frequency of the to-be-measured building according to the correction data; and performing safety assessment on the to-be-tested building according to the natural vibration frequency. According to the method of the invention, the health monitoring of the building structure is realized without depending on manual detection, the detection cost is reduced, and the efficiency of building safety assessment is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of building detection, and in particular to a building safety assessment method, device, equipment, and storage medium. Background technique [0002] With the development of society, urban buildings are increasing day by day, and a large number of new and complex building structures appear in civil engineering. In order to ensure the safe use of buildings in daily life and office work, it is necessary to monitor the health of the building structure and evaluate the safety of the building. [0003] The traditional method of building safety assessment is to determine some parameters of the building through manual inspection, and then conduct safety assessment of the building according to the obtained parameters. This evaluation method relies on manual completion, and the detection equipment and procedures are relatively complicated, with high cost and low efficiency. Contents of the in...
