Abstract

The invention relates to a single-side loading type large compression-shear-bending composite loading test device and application thereof. The device comprises a sunken terrace and a reaction wall arranged on one side of the sunken terrace, wherein a test piece accommodating pit used for accommodating a test piece is formed in the sunken terrace, horizontal guide rail actuating mechanisms are arranged on the two sides of the test piece accommodating pit correspondingly, a vertical actuating mechanism is arranged on each horizontal guide rail actuating mechanism, a loading frame matched with the top part of the test piece is arranged between the two vertical actuating mechanisms, and a horizontal actuating mechanism matched with the loading frame is arranged on the side face of the reaction wall. Compared with the prior art, the large-scale model test of a large-scale structural member can be realized, accurate loading of axial pressure, shearing force, bending moment and other load effects is strictly ensured, and the response property, mechanical property and failure mechanism of the large-scale structural member under various load combination effects, particularly, the hysteretic performance and the restoring force property of components can be conveniently researched.

Description

technical field [0001] The invention belongs to the technical field of civil engineering structure tests, and relates to a single-side loading type large-scale compression-shear-bending composite loading test device and its application. Background technique [0002] The development of high-rise building structures presents the following characteristics: the building volume is getting bigger and bigger, and the structure height is getting higher and higher. Therefore, seismic action and wind loads have an important influence in the structural design of tall buildings. Some large structural components, such as shear walls and giant columns, are widely used in high-rise buildings to resist horizontal and vertical loads. Therefore, the research on the mechanical properties and failure mechanism of large structural components is the key to structural design and the basis for ensuring structural safety. [0003] At present, when studying the mechanical properties and failure mec...
