Description
Technical Field
The utility model belongs to the technical field of buildings, and particularly relates to an out-of-plane displacement measuring device for a wall shear test.
Background
The in-plane shear performance of the wall is an important mechanical index for reflecting the anti-seismic performance of the wall, and the damage form of the wall in various structural systems influences the design and calculation of main stressed components.
At present, when a wall member is subjected to a shear test, the lower end of a wall body is usually fixed on a test platform, and then a horizontal load is applied to a certain position on the upper part of the wall body by using an actuator, so that the shear-resistant bearing capacity and the failure characteristics of the wall body are finally obtained. However, in the actual test process, if the center of the actuator is not aligned with the center line of the wall, the wall is easily twisted, so that the stress state of the wall is changed, and the stress condition of the wall cannot be accurately reflected. Therefore, during the wall test, it is usually necessary to measure the out-of-plane displacement thereof in order to fully consider the influence of torsion on the shear performance of the wall when analyzing the test results. The currently common method for measuring the out-of-plane displacement of the wall body is to adsorb a displacement meter onto an iron support through a magnet, and determine the out-of-plane displacement value through the change of the indication number of the displacement meter, but when the method is used for measurement, the position of a rod piece in the iron support is fixed, the sizes of different wall body members are changed, and when the arrangement conditions of the horizontal displacement meter and the vertical displacement meter are designed, the position of the rod piece of the support can be limited. The measurement of the out-of-plane displacement of walls of different sizes is very inconvenient.
