Abstract

The invention relates to a flexible, simple and convenient loading device for an anti-seismic property test. The device comprises constraint units for fixing test pieces to ground beams, a horizontal loading unit for applying a horizontal load to the test pieces and a vertical loading unit for applying a vertical load to the test pieces; the vertical loading unit comprises vertical jacks, vertical flexible pull rods and reaction beams located over the test piece, the lower ends of the vertical flexible pull rods are fixed with the ground beams, the upper ends of the vertical flexible pull rods are connected with the reaction beams, and the vertical jacks are fixed to the bottoms of the reaction beams and apply vertical loads to the top of the test pieces. According to the device, the vertical flexible pull rods are thin and long rod parts with the certain flexibility, when the test pieces generate horizontal displacement deformation under the action of the horizontal load, the vertical flexible pull rod can generate the certain curvature, and therefore the upper ends of the vertical flexible pull rods can horizontally move along with the reaction beams and the vertical jacks, that is to say, the relative positions between the vertical loading unit and the test piece do not change. The device is simple in structure and easy to install.

Description

technical field [0001] The invention belongs to the field of anti-seismic test devices, in particular to a flexible and simple loading device for anti-seismic performance tests. Background technique [0002] With the continuous development of the economy, my country's construction industry has also achieved rapid development. The application of building structures is also constantly developing and changing, mainly including masonry structure, frame structure, shear wall structure, frame-shear wall structure, tube structure, frame-core tube structure, etc. Nowadays, the country is vigorously promoting the development of industrialized buildings, and the impact of non-structural components on the performance of the main structure requires a certain amount of performance research. my country is a country prone to earthquake disasters. In order to ensure the safety of life and property, new buildings must meet very good seismic performance requirements. To this end, it is nece...
