Abstract

The present invention discloses a horizontal apparatus for component post seismic test. The apparatus comprises three parallel flange brackets and two groups of pull rods, and each group comprises four pull rods. The flange brackets are connected and fixed by four isometric pull rods. A jack is fixed in the middle of the flange brackets to pass axial force, and make the whole apparatus in a bearing self-balance state. The central part of the component post is connected to an MTS actuator through an adjustable connector adapter board. The apparatus has the advantages that: spherical hinge is used to easily fix a test piece and reduces the adverse impact caused by processing error, so as to avoid bias caused by conventional flat panel hinge. The apparatus has the advantages of simple structure, easiness to operate, less test space occupation and low requirements on the test apparatus.

Description

technical field

[0001] The invention relates to a simulation test device for bending and shearing of beams and columns under continuous axial compression, and is especially suitable for low-cycle reciprocating load tests of steel pipe concrete columns under continuous axial compression, and belongs to the field of civil engineering. Background technique

[0002] As a new type of composite structure, the steel tube concrete structure has been widely used because it has fully utilized the respective mechanical characteristics of steel structure and concrete. my country is an earthquake-prone country, and earthquakes bring huge losses to our country every year, so the research on the seismic resistance of CFST is very important. However, the traditional vertical test device has certain limitations. One is that in the traditional seismic test of vertical structural columns, a cuboid support needs to be poured for each specimen. When there are many specimens, the workload is hug...
