Multifunctional member earthquake-proof experiment device

Abstract

The invention discloses an anti-seismic experimental device of a multifunctional component. Its main loading methods are vertical and horizontal. It consists of two flange brackets, a box-shaped base, two sets of tie rods (each set of four threaded tie rods of equal length), an axial pressure control board, and two bowl hinges. The component is fixed with two bowl hinges, which are respectively fixed on the box-shaped base and the axial pressure control plate by bolts, and the adjusting screw is pushed through the jack fixed between the flange brackets to achieve the effect of applying axial force to the component. The fixture is tightly fixed in the middle of the component, and the fixture is connected with the actuator through the anchor rod to achieve the effect of applying lateral load to the component. The advantages of the invention are that it can be used for both vertical and horizontal types, small space occupation, easy disassembly, and convenient use, and during use, it can overcome unfavorable factors such as excessive deformation or instability, which can cause the components to fall or the axial force to be offset; The multi-functional component seismic experimental device has various functions, not only can meet the vertical loading conditions, but also can meet the horizontal loading conditions, and has low requirements for experimental equipment, and has a wide range of applications in experiments.

Description

technical field [0001] The utility invention relates to a simulation experiment device for the bending and shearing action of beams and columns under the action of continuous axial pressure. It is mainly used in the mechanical performance experiments of beams and columns, especially for the experiments of low cycle reciprocating loads of concrete filled steel tube members under the action of axial compression. Belongs to the field of civil engineering. Background technique [0002] With the rapid development of my country's construction industry and the promotion and application of concrete filled steel tube structures in practical engineering, concrete filled steel tube structures, as a composite structure with superior mechanical properties, have been more and more widely used in engineering. China is located between two major seismic belts in the world—the circum-Pacific seismic belt and the Eurasian seismic belt. It is a country with frequent earthquakes. The life and ...
