Embodiment

[0042] At present, in order to analyze the torsional component of the building or the torsional amount of the component, the torsional component is obtained by monitoring and calculating the translational momentum, and the acceleration values ​​of the three components are obtained by measuring the three-component acceleration sensor and the three-component acceleration sensor respectively, and then through equal division. The algorithm calculates the torsion of the building, and then deduces the torsion of building beams, columns and other components. However, this method obtains the torsional component indirectly through calculation through measurement of the translational component. There are many problems such as large calculation errors, difficult determination of the torsion center, and serious discrepancies between the torsion of components and the actual situation.

[0043] Another method is to analyze the torsion of the building structure and its components through comp...

Abstract

The invention provides a torsion amount measuring device and method, and relates to the technical field of building safety performance detection. The torsion amount measuring device comprises a first installation part which is configured to be installed on a to-be-measured part; a second mounting piece which is provided with a first tooth part, the second mounting piece is configured to be mounted on the to-be-tested piece, and the second mounting piece and the first mounting piece are arranged at an interval in the axial direction of the to-be-tested piece; a rotating piece which is rotatably mounted on the first mounting piece, and the rotating piece is provided with a second tooth part used for being meshed with the first tooth part; and a rotation measuring assembly is used for acquiring the rotation amount of the rotating part. The first mounting piece and the second mounting piece define a test section on the to-be-tested piece, the rotating piece rotates under the external force of earthquakes, wind and the like, the rotating measuring piece obtains the rotation amount of the rotating piece, and the relative torsion amount of the two ends of the to-be-tested piece is indirectly calculated through the transmission ratio of the first tooth part and the second tooth part. Due to the fact that rotation of the rotating piece is caused by external force such as earthquakes and wind in the environment, the error of the obtained torsion amount is small, and the reference value is large.

Description

technical field [0001] The present application relates to the technical field of building safety performance detection, in particular, to a torsion measurement device and method. Background technique [0002] At present, with the development of the economy, a large number of high-rise and super high-rise frame structure buildings and some special special-shaped buildings have appeared. Beams and columns are important basic components of these buildings and play a vital role in their support and load-carrying. However, under the action of external forces such as earthquakes and winds, in addition to bending, these beams and columns will also be torsion due to the eccentricity of the building structure or the action of external moments. Through post-disaster investigations, it can be found that torsional damage is an important cause of building damage. one of the factors. However, under the action of external forces such as earthquakes and winds, it is difficult to obtain the...
