Device and method of self-balancing portable automatic control shear wall horizontal vertical load common effect performance test

Abstract

The invention discloses a device and a method of a self-balancing portable automatic control shear wall horizontal vertical load common effect performance test. The testing device comprises a loading frame device, a test-piece fixing device, a test-piece loading device and a data collection system. The loading frame device comprises a ladder-shaped horizontal counterforce frame, an H-shaped steel girder bearing platform, a beam, an upright and a prestressing force wire rope. The lower end of the ladder-shaped horizontal counterforce frame is fixedly connected with one end of the H-shaped steel girder bearing platform, the upper end of the ladder-shaped horizontal counterforce frame is fixedly connected with one end of the beam, and the prestressing force wire rope is arranged in the ladder-shaped horizontal counterforce frame. The test-piece fixing device comprises two triangular steel frames, two fixing actuators and two sets of steel plates, wherein the triangular steel frames are fixed on the H-shaped steel girder bearing platform, and each triangular steel frame is connected with one fixing actuator. The device and the method of the self-balancing portable automatic control shear wall horizontal vertical load common effect performance test has the advantages of being simple in structure, convenient to disassemble, lower than before in needed materials, not only suitable for scientific research, but also suitable for test on hysteretic performance of a shear wall test-piece in a construction site.

Description

technical field [0001] The invention relates to a self-balancing portable automatic control shear wall horizontal and vertical load interaction performance test device and method, belonging to the field of concrete construction. Background technique [0002] In the field of civil engineering, the shear wall is the main lateral force-resisting member of the structure, so it is very important to study its hysteretic performance. [0003] At present, in the research on the hysteretic performance of concrete shear walls, the vertical force is mainly applied through the jack, but when the wall moves sideways under the horizontal load, the jack does not move sideways with the specimen, resulting in experimental errors ; During the loading process, the lateral movement of the bottom of the specimen also has a great influence on the test accuracy. Contents of the invention [0004] The invention provides a self-balancing portable automatic control shear wall horizontal and vertic...
