Seismic test device for fabricated cold-formed thin-walled steel walls and installation method thereof

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.

Problems solved by technology

[0004] The purpose of the present invention is to propose a kind of anti-seismic test device and installation method of assembled cold-formed thin-walled steel wall, to solve the shortcomings of traditional test devices

By using high-precision and low-friction linear guides instead of horizontal slides in traditional test devices, the problem of large errors in test results caused by large frictional resistance is solved; at the same time, out-of-plane supports are set to solve test errors caused by torsional instability of the wall ;By improving the cross-sectional form of the bottom beam and the loaded top beam, the actual boundary conditions of the prefabricated cold-formed thin-walled steel wall can be realized
