The multifunctional combination support meets support requirements of different types of pressure mechanics experiments of building components in civil engineering, simplifies the experiment process, improves the convenience of various pressure mechanics experiments, and provides more tangible experiment guarantee for exploring an axial pressure and unsymmetrical pressure bearing capacity calculating formula of different types of upright columns.

Description

technical field [0001] The invention relates to a multifunctional combined support for vertical loading test of a column and an implementation method thereof, belonging to the technical field of civil engineering. Background technique [0002] Compared with the traditional reinforced concrete structure, the steel structure has the characteristics of green environmental protection, good seismic performance, fast construction speed, and recyclable materials. With the rapid development of the national economy, my country's steel output has leapt to the first place in the world, and the domestic steel structure industry has also developed rapidly. However, compared with developed countries, the proportion of steel structure buildings in my country's steel production is still significantly low. Significant gaps still exist. my country is in the stage of rapid industrialization and urbanization, the annual project construction volume is huge, the resource consumption is serious, ...

Problems solved by technology

[0004] Technical problem: In order to overcome the deficiencies in the prior art, the present invention provides a multi-functional support capable of realizing single-direction, continuous fixed-value eccentric loading test and its implementation method, so as to meet the requirements of vertical loading test of steel keel columns. The requirements of load eccentricity and hinged boundary conditions; take into account the existing technology, the fixture function is single, the eccentricity accuracy is poor, the eccentricity cannot be achieved continuously, and the problems of various experimental requirements cannot be met at the same time; the axial pressure of civil engineering columns has been improved. The convenience of the test provides a more practical technical guarantee for the experimental research of axial pressure for various purposes (such as exploring the calculation formula of axial pressure and bias bearing capacity, etc.)
