The invention discloses a one-way eccentric hinge support and a use method thereof, and belongs to the field of constructional engineering. The one-way eccentric hinge support comprises a base, a load-bearing plate is arranged above the base, first connecting plates are fixedly arranged on the lower surface of the load-bearing plate, second connecting plates are fixedly arranged on the upper surface of the base, and the first connecting plates are hinged to the second connecting plates in a relatively rotatable mode; at least two sets of sliding baffles are arranged on the load-bearing plate, the sliding baffles slide along the load-bearing plate, therefore, the sliding baffles clamp a test component, and the test eccentricity of the test component is adjusted. The one-way eccentric hinge support is easy to machine and convenient to install and use, and all parts are easy to store after being disassembled. The support is suitable for tests of axial compression, axial tension, eccentric compression, eccentric tension and the like, and an ideal use effect can be achieved.
