Abstract

The invention relates to a framework column bending hysteresis test specimen with reusable stiffening bar sections, belonging to the field of building structure member experimental studies, and solving the problem of high cost, big waste and the like of the traditional framework column bending hysteresis performance test in which bar sections arranged at the two ends of a framework column can be used only once. The test specimen disclosed by the invention comprises a column shaft and two stiffening bar sections; the upper end and the lower end of the column shaft are each provided with a stiffening bar section; the two ends of the column shaft can be detachably connected with an I-shaped steel bar sections of the stiffening bar sections by a stiffening lug plate and a connecting annular plate welded on the column shaft; or the two ends of the column shaft can be detachably connected with the I-shaped steel bar sections of the stiffening bar sections by the stiffening lug plate and theconnecting annular plate of a steel tube column head fixed on the column shaft. When the test is completed, connecting pieces for connecting the stiffening lug plate and steel bar section web plates and connecting the annular plates and the inner edges of the steel bar sections are detached, so that the stiffening bar sections at the two ends of the column shaft can be reused.

Description

technical field [0001] The invention relates to a test piece used in the hysteretic performance test of frame column compression bending, which belongs to the field of test research of building structural components. Background technique [0002] Frame column compression bending hysteresis performance test is one of the important means to study the seismic performance of building frame columns and establish the seismic design method of frame columns, including reinforced concrete columns, steel columns, steel tube concrete columns, steel concrete columns and other types of frame columns . At present, when carrying out the frame column compression bending hysteresis performance test, a beam section with high rigidity is generally set at each end of the frame column to simulate the rigid connection mode of the frame column and the frame beam in the actual structure, and at the same time it is convenient The test piece is connected and fixed with the loading device, and the be...
