Embodiment Construction

[0032] specific implementation plan

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] A low-cycle repeated loading test device, such as figure 1 . The test device includes: a steel column 1 , a first upper outer frame beam 2 , a second upper outer frame beam 3 , a roller 4 , a jack 5 , a U-shaped welded channel steel 6 , and a roller 7 .

[0035] The test object component 8 needs to be connected to the abutment through the ground beam 9 and then installed in the middle of the low cycle repeated loading test device, see Figure 7 .

[0036] The steel column 1 is an I-beam with equal cross-section, and the flanges are provided with bolt holes at equal intervals, see figure 1 .

[0037] The first upper outer frame beam 2 and the steel column 1 are fixed by the bolt holes on the end plate of the upper first outer frame beam 2 and the bolt holes corresponding to the bolt holes on the wing plate of t...

Abstract

The invention relates to a low-cycle repeated loading test device. The low-cycle repeated loading test device is characterized by comprising a steel column (1), a first upper outer frame beam (2), a second upper outer frame beam (3), a rolling shaft (4), a jack (5), a U-shaped welded steel channel (6) and a roller (7). The device has the advantages that the device can regulate a position of a lateral limiting device according to a size of a test piece, implements effective out-of-plane constraint on the test piece and limits out-of-plane instability of the test piece, so that the test piece isdeformed in a plane and a stress condition of the test piece under the in-plane horizontal low-cycle repeated load action is simulated to the greatest degree; and the integral set of device is simpleto mount and disassemble and can be recycled, so that test expenses are obviously reduced.

Description

technical field [0001] The invention relates to a loading device, in particular to a low cycle repeated loading test device. Background technique [0002] Low-cycle repeated loading test refers to the static test that applies multiple reciprocating cycles to the structure or structural components. It is the process of repeatedly loading and unloading the structure or structural components in both positive and negative directions. Stress characteristics and deformation characteristics in reciprocating vibration. This method uses the static method to obtain the effect of structural vibration, so it is called pseudo-static test, or pseudo-static test. The low-cycle repeated loading test of structures is one of the most widely used methods to study the stress and deformation performance of structures or structural components. [0003] In the traditional low-cycle repeated loading test, the specimen may be unstable in the direction of greater out-of-plane compliance under the e...
