Embodiment Construction
[0043] The following is attached Figure 2-4 The present invention is described in further detail.
[0044] An embodiment of the present invention provides a building vibration modal testing method, comprising the following steps:
[0045] Step S100, according to the currently detected building, the test points are distributed and arranged according to the A strategy, and the analysis frequency is selected and the sampling time length is set; wherein the sequence of the test floors is determined according to the layout diagram or plan of the test points.
[0046] Strategy A is: first, test points are set on each floor of the building and the sensors at the vertical test points are connected to the same collector; second, the collector corresponds to the mobile device one by one; third, according to the tested The building chooses the type of sensor installed at the test point; sensor types include:
[0047] a——horizontal sensor, vertical sensor;
[0048] b - level sensor; ...

The invention discloses a building vibration mode testing method, which relates to the technical field of building testing, and solves the problems of inconvenience, time waste and labor waste in running of personnel carrying a notebook computer at different positions. The method comprises the following steps that testing points are distributed and arranged by adopting a strategy A, wherein the strategy A is as follows: firstly, each main floor of the building is provided with a testing point, and each sensor at the same position of different floors is connected to the same acquisition instrument, and secondly, the acquisition instruments are in one-to-one correspondence with the mobile devices; a wire is arranged and a sensor is fixedly arranged; and corresponding mobile computer displaydevices are in one-to-one correspondence so as to facilitate setting and operation, and data transmission, checking and integrity and reliability rechecking are carried out on the mobile computer after acquisition is finished. According to the building vibration mode testing method, on the basis of not increasing the number of acquisition equipment and personnel, on-site data acquisition can be smoothly realized.
Description
technical field [0001] The invention relates to the technical field of building testing, in particular to a building vibration mode testing method. Background technique [0002] Building vibration has attracted more and more attention. In order to obtain the vibration modal response of different parts of the structure at the same time, multiple sets of tests are required. [0003] For example, in a building with a large plane size, such as a shopping mall building larger than 100m, such as figure 1 As shown, the traditional way of building vibration modal testing is usually to set several vibration test points on each floor, and the staff will take the collector and computer to each test point to obtain test data in turn. [0004] However, due to the long space between the test points on each floor, it is inconvenient for personnel to run with the collector and computer at different locations. Once the last test point or the current test point is wrong, the staff have to go...
