Method for measuring high-rise building drift displacement

Abstract

A method for measuring drift displacement of high building includes setting tiltmeter on observation point at certain height of high building to measure dip angle of high building at observation point then enabling to accurately calculate out drift displacement of observation point according to height difference of multiple set observation point and said dip angle.

Description

technical field [0001] The invention relates to the field of measuring drift displacement of buildings, in particular to a method for measuring drift displacement of high-rise buildings. Background technique [0002] With the development of the economy, there are more and more high-rise and super high-rise buildings, especially super high-rise buildings like Jinmao Tower, which not only have very detailed theoretical design parameters, but also have theoretical vibration parameter values ​​of the buildings when they are subjected to earthquakes and typhoons. Observing the actual vibration of such a building and performing appropriate calculations can not only test the deviation between the actual observation results and the theoretical design, but also detect the performance of the building's own structure, which can provide guidance and reference for the design of super high-rise buildings in China value, which is beneficial to the design of similar structures in the future...

AI Technical Summary

Problems solved by technology

However, the displacement measured by the general vibration measuring instrument is under the premise that the random vibration is small or relatively small amplitude, and the high-rise building has a large drift due to its high height, and the existing measurement methods and Equipment, for measuring vibrations whose amplitude is in the order of meters, there are not many suitable instruments for measurement, and the measurement accuracy and frequency band are limited

In addition, since the displacement of high-rise buildings at different heights does not change linearly during the process of force drift, it is not scientific enough to measure at one observation point and then calculate the displacement at other positions for the measurement of different heights
