Abstract

The invention relates to a structure test system with a tension-compression bending shear force applying function. The structure test system comprises an L-shaped beam (3), a horizontal force applyingdevice (1), a vertical force applying device (2) and a sample support (6), the L-shaped beam comprises a horizontal portion and a vertical portion which are integrally connected, the bottom surface of the middle of the horizontal portion is in rigid connection with the upper potion of a sample, one end of the horizontal force applying device is connected with a reaction frame or reaction wall surface, the other end of the horizontal force applying device is connected with is connected with the vertical portion of the L-shaped beam (3), the upper end of the vertical force applying device (2) is hinged to the bottom surface of the horizontal portion of the L-shaped beam (3), and the lower end of the vertical force applying device (2) is hinged to the ground, and the sample support (6) is inrigid connection with the lower portion of the sample. Compared with the prior art, the structure test system applies horizontal acting force and vertical acting force through the horizontal force applying device and the vertical force applying device, and tests under unidirectional tension, compression and shearing or tension (compression), bending and shearing composite action can be performed.

Description

technical field [0001] The invention relates to a structural test device, in particular to a structural test system capable of applying tensile, compressive, bending and shearing forces. Background technique [0002] In the fields of construction, machinery, etc., it is often necessary to test the specimen under unidirectional tension, shear or tension (compression) bending-shear composite action to test the mechanical properties of the specimen under these stress states. [0003] Existing test devices can only realize the compound state test of two kinds of force, and it is difficult to test the compound effect of three kinds of force. Contents of the invention [0004] The object of the present invention is to provide a structural test system capable of applying tensile, compressive, bending, and shearing forces in order to overcome the above-mentioned defects in the prior art. [0005] The purpose of the present invention can be achieved through the following technical...
