Test device for civil engineering frame structure

Abstract

The invention belongs to the technical field of civil engineering tests and discloses a test device for a civil engineering frame structure. The device is provided with a plane design characteristic system of a test piece, a vertical design characteristic system of the test piece and a test installation system, a load implementation system applied with a building structure constant load characteristic and a load implementation system applied with reciprocating loads are represented through the installation system. The plane rigidity, bearing capacity and test cost of a structure model are remarkably reduced, the plane rigidity is reduced by more than 10 times, the bearing capacity is reduced by more than 5 times, and the test cost is reduced by nearly 2 times. For the bearing capacity, thetest which can be completed by 800 tons of horizontal force originally can be completed by less than 200 tons of horizontal force at present, and the test quality is equivalent. The test effect of planar arrangement reserves the advantages of a shape like a Chinese character 'rice field' and supplements the defects of a square shape, the test difficulty is reduced, and the mode of the invention is an ideal test piece mode for researching the frame structure.

Description

technical field [0001] The invention belongs to the technical field of civil engineering tests, in particular to a test device for a civil engineering frame structure, which includes a test piece system and a load system. Background technique [0002] In the structural laboratory, the basic test of the structural test is a single component test, such as beams, slabs, columns, joints, supports, foundations and other stressed parts. The test technology is less difficult and easy to implement, but it can only stand After understanding the structure from the side, after considering the structure as a whole, especially after considering the effect of the structural space, the research on the components only observes and verifies the structural characteristics of the components themselves, but cannot observe and verify the structural characteristics of the components after the coordinated deformation of the overall structure. limitation. Therefore, the understanding of the overal...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problems existing in the existing technology are: for the test of a single component, although the test is less difficult and easy to organize, it is difficult to achieve the purpose of investigating, understanding and verifying the overall performance of the structure; The test load of the specimen test is large, the test cost is high, and the test is difficult; while the test of the "mouth"-shaped plane layout specimen with less test difficulty is not representative of the performance of the frame structure
