Problems solved by technology

[0003] At present, the loading device of the low-cycle repeated loading test device includes a horizontal loading device and a vertical loading device. In the prior art, since the loading end of the loading device is fixed, the wall member to be tested is subjected to low-cycle repeated loading during the loading process. It is very easy to cause serious eccentricity and torsion due to lack of lateral support, and it is also easy to limit the structural deformation due to excessive restraint, which makes the error of the test data large and it is difficult to obtain more accurate test data

Abstract

The invention provides a wall-type component lateral support device and a low cycle repeated loading test device. The lateral support device comprises one pair of lateral support bodies. One pair of lateral support bodies is fixedly connected through a connection support. One end of each lateral support body is vertical to a pulley group arranged along a length direction. The pulley group can be pressed against the surface of a wall-type component to be tested and can be rotated under the vertical or horizontal force applied by a loading device to the wall-type component to be tested. The other end of the lateral support body is a free end. The free end can be embedded in the lateral support beam of the low cycle repeated loading test device. By using the wall-type component lateral support device, a practical problem that the wall-type component to be tested is not deformed or twisted in a same plane during a low cycle repeated loading test process is solved, and the accuracy and thereliability of a test are effectively increased.

Description

technical field [0001] The invention relates to the technical field of low-cycle repeated loading test equipment, in particular to a lateral support device for a wall-type component and a low-cycle repeated loading test device. Background technique [0002] The low-cycle repeated loading test, also known as the static test or quasi-static test, refers to the low-cycle repeated loading of the wall components to be tested by controlling the load or displacement to study the recovery characteristics and The energy dissipation capacity, and then judge and appraise the seismic performance of the wall components to be tested from the three aspects of strength, deformation and energy, and provide a basis for improving the seismic design method and modifying the seismic design of buildings. [0003] At present, the loading device of the low-cycle repeated loading test device includes a horizontal loading device and a vertical loading device. In the prior art, since the loading end o...
