Abstract

The invention discloses a seismic test device for fabricated cold-formed thin-walled steel walls and an installation method thereof, which belong to the technical field of architectural engineering structure test. The seismic test device for fabricated cold-formed thin-walled steel walls includes a fabricated cold-formed thin-walled steel wall, a bottom beam, a loading top beam, a linear guide rail, an out-of-plane support device, jacks, a distributive girder, bottom beam pads, a reaction frame, high-strength bolts, anchor bolts, and the like. The out-of-plane support device is connected to the top beam of the reaction frame to constrain the wall and prevent the wall from being destabilized. The seismic test device for fabricated cold-formed thin-walled steel walls not only can make up for the shortcomings of the traditional wall test device, but also can accurately simulate the real boundary conditions of cold-formed thin-walled steel walls. The test result obtained is accurate and reliable. The safety risk in test and the test cost are effectively reduced. The seismic test device is of great practical significance in the test of fabricated cold-formed thin-walled steel walls.

Description

technical field [0001] The invention relates to an anti-seismic test device for an assembled cold-formed thin-walled steel wall and an installation method thereof, belonging to the technical field of construction engineering structure tests. Background technique [0002] The traditional cold-formed thin-walled steel wall seismic test device consists of a reaction frame, a test bench, a test wall, a loading top beam, a horizontal slide plate, a horizontal jack, and a vertical jack. The bottom of the test wall is connected to the test bench, the top of the test wall is connected to the loading top beam with high-strength bolts, the end of the loading top beam is connected to the horizontal jack, the top of the loading top beam is connected to the bottom of the vertical jack, and the top of the vertical jack is connected to the bottom of the slide plate , the top of the slide plate is connected with the top beam of the reaction force frame. This type of test device has the adv...
