Abstract
The invention provides a device and an implementation method for keeping an extended steel plate out of instability first in a pressed steel component test. A steel component comprises a cantilever steel plate which extends towards two sides. The device for keeping the extended steel plate out of instability first in the pressed steel component test comprises a pair of temporary stiffened plates arranged on the two sides of a steel component test piece respectively, wherein a clamping side of the cantilever steel plate is clamped between the pair of temporary stiffened plates on the same side;the temporary stiffened plates and the cantilever steel plate are arranged in parallel; and the pair of temporary stiffened plates on the same side are connected through bolts penetrating through thetwo temporary stiffened plates, and the bolts are not in contact with the cantilever steel plate, so that the device not only restrains part of the steel plate extending out of the cantilever but prevents from introducing redundant variables to a local stability test. The device is reasonable in stress, scientific in design, excellent in durability and capable of being recycled.
Description
technical field [0001] The invention relates to a device for keeping protruding steel plates from losing stability in the test of steel components under pressure and its implementation method. Background technique [0002] In steel structures, many test pieces have the form of protruding steel plates. For example, box steel structures, I-beams, stiffeners with closed ribs or stiffeners with open ribs. When carrying out the local stability test of these steel structures under compression, the protruding steel plate often loses stability first, and the instability performance of other plates other than the protruding steel plate cannot be obtained. In order to ensure that the protruding steel plate does not lose stability first , often using a shorter protruding steel plate specimen structure for testing. The use of a short protruding steel plate makes the specimen lose its symmetry, resulting in changes in the residual stress of the component, which introduces redundant var...
