Abstract
The invention discloses a structural member torsion test method and device. One end of a structural member test specimen is fixed on the structural member torsion test device, and the other end is inserted into a sleeve; the other end of the sleeve is connected with a threaded rod; the threaded rod is fixedly connected with a hydraulic jack on the torsion test device, so that while the hydraulic jack makes the threaded rod perform axial movement, because of the presence of a threaded rod thread and a sleeve threaded hole lead angle, a component force perpendicular to the sleeve radial direction can be generated through interaction of the threaded rod thread and a sleeve threaded hole thread; the component force generates a rotating force moment on the sleeve, and thus the sleeve applies a torque to one end of the structural member test specimen; through the method, the torsion test can be carried out on the structural member test specimen. The method and the device fundamentally solve a theory problem of torsion-resistant structural members and a theory and practical application combined problem, and are especially suitable for research use in pure torsion, bending torsion and compression torsion tests of constructional engineering large structural members.
