Problems solved by technology

Although the vibration response of towering structures is tested in groups, although the number of vibration test acquisition devices (such as sensors) and the limitation of test capabilities are solved, there are still some defects: (1) Due to the deviation of instrument collection and analysis, the sensor is damaged Or external environmental disturbances and other influences will generate errors in the layer-by-layer test process, and the errors will continue to accumulate and gradually increase, which will seriously affect the accuracy of the test data, or even errors; (2) due to the limitations and Insufficient, it will lead to inaccurate analysis of the transfer characteristics of the vibration of towering structures, and lose the significance of vibration testing of towering structures

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the examples, but the present invention is not limited to the following examples.

[0020] Such as figure 1 As shown, the present invention provides a multi-point synchronous test method for different-layer vibration of a towering building structure, comprising the following steps:

[0021] (1) Measuring point layout: Through the analysis of the structural characteristics of towering buildings, determine multiple key layers that need to be tested for vibration, and arrange measuring points in each key layer;

[0022] The response of a building to vibration is related to factors such as the building structure, and the layout of the measuring points should take the building structure into consideration. It is a very important issue for a building structure to pick up its vibration signal from which part to get the expected effect. The pickup of the vibration signal depends on the layout of the sen...

Abstract

The invention discloses a heterosphere vibrating multi-point synchronization testing method of a towering type building structure; the method includes steps of (1), layout of testing points: confirming multiple key layers required to perform vibration test through analyzing characteristics of the towering type building structure, and arranging testing points in every key layer; (2), grouping of testing points: grouping the testing points according to the grouping method of overlapped testing points, wherein the grouping method of overlapped testing points is that every group contains equal number of testing points, and adjacent groups have at least one overlapping testing point; (4), vibration test: performing vibration test on every group, and acquiring the testing data; (5), data analysis: analyzing the vibration testing data, comparing the vibration parameters of the overlapped testing points tested by two times, and confirming the validity of the testing data. Based on the method of performing vibration testing by grouping, at least one overlapped testing point is distributed to adjacent groups, and judgment and calibration are carried out through the vibration parameter of the overlapped testing points, thereby effectively guaranteeing the effectiveness of the testing data.

Description

technical field [0001] The invention relates to the technical field of vibration testing of building structures, in particular to a multi-point synchronous testing method for different-layer vibration of towering building structures. Background technique [0002] At present, there are mainly two technical methods for vibration testing of towering building structures: [0003] The first is to use a large-scale vibration test device to conduct a carpet-type and full-coverage test, but this test method has the following limitations: [0004] (1) When large-scale vibration test devices are used at the same time, the sensors are required to be strictly synchronized in time and space, but working together for a long time will cause instrument errors (such as GPS errors, etc.), making it difficult to achieve real synchronous testing. The asynchronous nature of the test will cause inaccurate data; (2) cannot accurately reflect the transfer characteristics of the vibration of differ...
