A test device for civil engineering frame structure

Abstract

The invention belongs to the technical field of civil engineering testing, and discloses a test device for a civil engineering frame structure, which is provided with a plane design feature system of a test piece, a vertical design feature system of the test piece, and a test installation system; through the installation system A load implementation system representing the dead load behavior of an applied building structure and a load implementation system representing applied and complex loads. The plane rigidity, bearing capacity and test cost of the structural model of the present invention all show the characteristics of significant reduction, 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. In terms of bearing capacity, the test that originally required a horizontal force of 800 tons can be completed now with a horizontal force of less than 200 tons, and the test quality is equivalent; the test effect of the plane layout of the present invention retains the "field" shape. It complements the shortcomings of the "mouth" shape and reduces the difficulty of the test. It is an ideal specimen model for studying frame structures.

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
