Multifunctional structure engineering loading test system

Abstract

The invention provides a multifunctional structure engineering loading test system. The system comprises a counterforce frame, a horizontal actuator unit, a loading beam, a vertical actuator unit, a first connection part, and a second connection part; one end of the horizontal actuator unit is hinged with the counter-force frame, and the other end is hinged with the loading beam; the first connection part is arranged on the loading beam, one end of the vertical actuator unit is connected with a second connection part, the second connection part is connected with the first connection part, thereby enabling the vertical actuator unit to make fitting curve movement on horizontal and vertical directions by following a loading point; the other end of the vertical actuator unit is connected withthe counter-force frame; the space between the loading beam and the counter-force frame is used for placing a test piece. The vertical actuator can follow the loading point to make fitting curve trajectory follow-up at the horizontal and vertical directions without a specific follow-up device, the structural part can conveniently perform pressing, bending and shearing and multiple composite typeloading test.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to a loading test system, in particular to a structural engineering loading test system. Background technique [0002] Structural tests are to prevent accidents and casualties in buildings and other facilities when external forces occur. For this reason, a lot of research has been done on structural performance, and a large number of tests have been carried out to verify the design theory. Loading and unloading of the specimen is performed as a control value. [0003] At present, the vertical loading forms of structural seismic tests adopted at home and abroad include: passive sliding type, active tracking type, upper bearing type, pull-down type, modular tie rod type, etc. These loading devices can implement loading control together with the horizontal loading system, or can be loaded independently. [0004] The main problems in the vertical loading systems of passive sli...

AI Technical Summary

Problems solved by technology

The disadvantage of the modular tie-rod loading system is that the tie-rod can only bear tension, not pressure, and cannot carry out small axial compression ratio loading tests, nor can it do more complex composite tests such as compression, bending and shearing.

In addition, the base of the test piece usually needs to be made relatively large, and the cost of experiment input is relatively large
